Historical Development
Since the rise of the plastics industry, polypropylene has been widely used in the world, but the problem of fire prevention still exists, and craftsmen have thought hard about good strategies. Red phosphorus has been used for resin mixing for its high-efficiency flame retardant properties, but the light and oxygen are unstable, the color is easy to darken, and the application is not full. With the advanced craftsmanship, red phosphorus masterbatch is produced, and polypropylene and red phosphorus are combined with ingenuity, so that the particles are evenly distributed, and the performance is significantly improved. The technology is more and more perfect, the carrier is stable and protective of red phosphorus, and it is safe and reliable. It is used in spinning, injection molding, and extrusion. When things are available, they are widely used, and the way of environmental protection and flame retardancy is gradually ready. Today's red phosphorus masterbatch has stable color and worry-free storage and transportation, which makes polypropylene products more secure, and
Product Overview

Its application can not only be thermoformed, but also suitable for spinning and injection molding, which can reduce combustion hazards and effectively protect the safety of personal and property. It is especially suitable for high-end flame retardant needs, light and environmentally friendly, and has a wide compatibility. It is easy to operate, and the effect is obvious when blended in an appropriate amount. It is properly matched and not afraid of splash pollution. It is respected by modern industrial processing and is an indispensable product in the industry.
Physical & Chemical Properties
The red phosphorus masterbatch of polypropylene has a bright color and uniform soil. It is soluble in water and is not easy to disperse in multiple solvents. Its phosphorus particles are uniformly dispersed on the substrate to prevent agglomeration and increase its flame retardant effect. Under normal conditions, the properties are stable, and the light quality has a high tolerance. If the environment exceeds the boundary, there is a slight decomposition, and the phosphating is produced. However, under the shelter of polypropylene-based materials, this effect is large. The acid on the melting layer has a certain resistance, but there is a risk of reaction when it encounters oxidation. Its granularity promotes the flow of granules and the convenience of shaping. In short, the material code is mixed, which is effective and can be used in the process of multi-polymer.
Technical Specifications & Labeling
This product is called "polypropylene red phosphorus masterbatch", red in color, well-proportioned particle size, round particles. Its main ingredient is high-quality red phosphorus, supplemented by polypropylene carrier, red phosphorus content is commonly 20% -60%, users can customize according to needs. The density is about 1.1-1 grams per cubic centimeter, and the melt index (MFI) varies depending on the carrier, mostly between 5-30 grams per ten minutes. Excellent heat resistance, decomposition temperature is over 280 degrees Celsius. Good dispersion, suitable for a variety of resin substrates. Composite woven bags are commonly used in packaging, lined with film, net weight of 25 kg, moisture-proof and fireproof, and should be stored in a cool and dry place. The surface of the product is often marked with a specific logo, indicating the batch number, production date and manufacturer, to facilitate traceability inspection.
Preparation Method
Polypropylene is used as the base material, with red phosphorus particles as the main aid, supplemented by dispersants and antioxidant seasonings, and reconciled in proportion. The surface of red phosphorus is coated in advance, or chemically treated to prevent its oxidation. Then put it in a high-speed mixer and stir evenly. Afterwards, the red phosphorus particles are melted at high temperature through a twin-screw extruder, so that the red phosphorus particles are evenly distributed in the polypropylene melt. Extrusion cooling, granulation molding. The principle of catalysis is to use the self-chain structure of polypropylene to apply high temperature and mechanical shearing to promote molecular movement to facilitate the coating of additives and homogeneous dispersion. When exposed to high temperature, red phosphorus precipitates a phosphoric acid polymer, which can block oxygen and inhibit combustion. The masterbatch is obtained by this method, which has the effect of flame retardancy and is convenient for subsequent plastic processing applications.
Chemical Reactions & Modifications
Polypropylene is a commonly used polymer, which is lazy and difficult to flame retardant. Red phosphorus is an isomerism of phosphorus, which has high flame retardant properties. However, when mixed directly, it is easy to cause uneven dispersion, and there is also a risk of oxidation and spontaneous combustion. Today, with a polymer carrier to make phosphorus masterbatch, the method is to first fine the red phosphorus and coat it on the surface to isolate the air and inhibit the oxidation reaction. Then it is mixed into polypropylene and melt blended to make the red phosphorus evenly distributed. Red phosphorus interacts with oxygen at high temperatures to form phosphorus pentoxide, which then forms a phosphoric acid polymer, forming a dense carbon layer on the surface of polypropylene to block heat and oxygen, inhibit combustion and reduce the release of toxic gases. It is a combination of chemical reaction and modification that not only enhances the flame retardant properties of the material, but also ensures the safety of its processing and use, resulting in high-performance polypropylene flame retardant materials.

Especially in industries that prioritize safety protection and environmental protection, the demand for it is increasing day by day, and the application prospect is broad.
Research & Development
Since ancient times, it has been used for new products, and the process has become increasingly exquisite. Polypropylene red phosphorus masterbatch is an essential product for modern flame retardancy. Its development requires the selection of high-purity red phosphorus, which is evenly divided into polypropylene by scientific methods to prevent its precipitation and migration, and avoid the danger of spontaneous combustion of moisture gas. We refer to ancient books, integrate modern technology, and develop many coating technologies, or resin, or coupling agents, all of which are to improve compatibility and stabilize its flame retardant properties.

Toxicity Research
The master batch of polypropylene red phosphorus is mainly red phosphorus, with a polymer carrier, which is widely used in plastic flame retardant. However, red phosphorus is easy to oxidize, and when it encounters wet toxins, if it is not managed properly, there is a risk of explosion and poisoning. Today, according to the square masterbatch, red phosphorus is dispersed in the polypropylene matrix, and its escape is greatly reduced, and its toxicity is also reduced. However, when the meso-decomposition products are processed or burned at high temperature, if the conditions are improper, or there are toxic gases such as phosphine escaping, it is advisable to ventilate or add protection. If the human body is exposed for a short time, if there is no decomposition, the toxicity is minimal, but if it is exposed to high concentrations for a long time, it can still cause respiratory tract, eye and skin irritation. Therefore, its use should strictly abide by the operating procedures, store moisture and fire prevention, and avoid hot In short, the preparation of masterbatch to inhibit the activity of red phosphorus, the toxicity is greatly reduced than that of the original material, but it should not be taken lightly. It is necessary to prevent processing decomposition and accidental leakage to ensure the safety of personnel and the environment.

What are the main uses of Polypropylene Red Phosphorus Masterbatch?
Polypropylene Red Phosphorus Masterbatch, which is the red phosphorus masterbatch for polypropylene, has unique properties and is mainly used for flame retardant of polymer materials. Red phosphorus has been recognized as a good flame retardant since ancient times, while polypropylene is a polymer commonly used in modern industry. It is light and tough, but it is flammable and easy to be used for safety. Today, red phosphorus is refined into a fine powder, packaged by a special process, dispersed by a carrier resin, and combined into a masterbatch. Its color is purple-brown, heat-resistant and durable, and it is easy to blend with polypropylene resin. The polypropylene products obtained in this way decompose when exposed to fire, generating metaphosphoric acid, which can promote the surface of polypropylene to form carbon, isolate oxygen, and inhibit flame generation. The red phosphorus masterbatch is not easy to volatilize, and has high storage and transportation safety. Compared with other organohalogen flame retardants, it is environmentally friendly and halogen-free, and has no corrosion harm. It is widely used.
It can be used with this masterbatch for those who need flame retardancy and use polypropylene. Especially in electronics, electrical enclosures, automotive parts, furniture and building materials, packaging materials, textile utensils, etc. Compared with traditional flame retardant methods, red phosphorus masterbatch can be evenly distributed in polypropylene, and the amount used is less, and the flame retardant effect is remarkable. At the same time, it can maintain the mechanical properties of the material without damaging its own toughness and strength. It is widely used in fields that require high performance flame retardant. In addition, the combination of red phosphorus masterbatch with synergist and synergist can improve the flame retardant level to cope with harsh standards.
In summary, Polypropylene Red Phosphorus Masterbatch is an indispensable aid for the safety protection of polypropylene products in use today.

What is the addition ratio of Polypropylene Red Phosphorus Masterbatch?
The method of blending polypropylene and red phosphorus masterbatch requires reviewing the proportion of its addition to ensure that the product has both flame retardancy and mechanical properties, and to ensure the stability of quality. However, the red phosphorus masterbatch is obtained by precise dispersion and granulation of red phosphorus and carrier resin, and its red phosphorus content is usually about 40% to 50%. If you want to give polypropylene products excellent flame retardancy, you need to weigh the amount of addition according to the requirements of the flame retardant grade in the application.
Today, according to the prevailing norms, those who use polypropylene red phosphorus masterbatch to reach UL94 V-0 grade, the addition ratio is generally between 5% and 10%. If only V-2 grade is required, or those with lower flame retardant requirements, the dosage may be appropriately reduced to 3 or 4%. However, it is necessary to consider the risk of flame expansion and dripping, and be careful not to take it seriously.
When blending, it is necessary to take into account the uniform dispersion of red phosphorus and the changes in the physical properties of the base material. Add too much, or cause fading, brittleness, and increase costs; if the amount is too small, the flame retardant effect will not be ideal. Therefore, it is often used in the middle of 5 to 8%, which can not only ensure the stability of the product, but also meet most flame retardant specifications. During the process, the masterbatch and polypropylene resin must be evenly stirred to prevent the masterbatch from aggregating and causing uneven flame retardancy. It should also be moisture-proof and oxygen-proof, and stored properly to prevent red phosphorus from self-igniting due to moisture.
It should also be noted that red phosphorus has a certain risk of oxidation and flammability. Operators should use protective facilities and properly isolate it in a high-temperature and humid environment. Such as cable coating and electronic product shell, red phosphorus masterbatch can be applied according to the above ratio. The finished product can not only meet the flame retardant standard, but also take into account the color and strength, which is a good policy for modern industry.
In summary, the master batch of polypropylene red phosphorus is usually 5% to 8%, and the special needs can be increased or decreased. In practice, users should choose flexibly according to the characteristics of raw materials, product specifications and flame retardant standards, and weigh all aspects to achieve the best results.

How is the flame retardant effect of Polypropylene Red Phosphorus Masterbatch?
Polypropylene red phosphorus masterbatch is specially used for the flame retardant of polypropylene. Its properties are famous in the industry, and it is called flame retardant and effective. Red phosphorus, which is not gold stone, is actually one of the variants of phosphorus, with stable properties. In case of high temperature, phosphoric acid will occur, which can isolate air and cut off the source of combustion. If it is combined with polypropylene and made into a masterbatch, its dispersion performance is excellent, and it is easy to add. It can be evenly integrated into the polypropylene resin without damage to the appearance, and the flame retardant effect is more and more obvious.
Polypropylene is flammable in nature, and it melts and drips quickly in case of fire, and the fire spreads and is difficult to self-extinguish. The addition of red phosphorus masterbatch, under the action of heat, precipitates phosphoric acid, which prompts the formation of a carbon Its film is dense and firm, shielding oxygen, inhibiting heat transfer, and preventing the release of combustible gas. At the same time, red phosphorus does not escape toxic gases, nor does it have halogen pollution. It is green and environmentally friendly, and is in line with the times.
In experimental terms, the content of Polypropylene red phosphorus masterbatch is often 2% to 10%, which can make polypropylene products reach UL94 V-0 or V-2 grade. When the flame encounters its products, it is more common to see short flames self-extinguishing, less dripping, and the fire is difficult to develop. Its flame retardancy varies with uniform dispersion and quality control of the masterbatch, but it is always better than simple red phosphorus powder for dispersion and safer operation. Red phosphorus masterbatch has excellent thermal stability, and does not cause white smoke or spontaneous combustion at processing temperature, ensuring stable production and clean and beautiful products.
However, there are also those who need to be prevented, such as red phosphorus is sensitive to moisture, and there is a risk of oxidation if it is kept wet for a long time. Storage and mixing should be moisture-proof and sealed, away from strong oxidants and hot topic sources. If the red phosphorus masterbatch is properly matched in polypropylene, it can maximize the flame retardant effect without compromising the mechanical strength and processing technology. As for the color, the red phosphorus masterbatch is slightly reddish-brown, and the product may affect the appearance, but the color scheme can be adjusted and remedied.
In short, Polypropylene red phosphorus masterbatch provides a strong flame retardant method for polypropylene products, taking into account safety and environmental protection, and is the first choice for modern polymer processing flame retardant. If it is used properly, polypropylene will become steel, and the fire will not spread, and the industry will benefit from it.

Does Polypropylene Red Phosphorus Masterbatch affect the physical properties of the product?
Polypropylene (Polypropylene) red phosphorus masterbatch is an important agent for fire retardant and flame retardant in the modern polymer material industry. Red phosphorus can significantly improve the combustion resistance of resins due to its unique chemical properties. However, its impact on the physical properties of products cannot be ignored.
The red phosphorus masterbatch is mixed with the polypropylene masterbatch to obtain its uniform dispersion, which is of great benefit to the flame retardant performance. When the red phosphorus is exposed to high temperature, phosphoric acid is precipitated, covering the burning surface to isolate oxygen and slow down the combustion rate. Mixed in a suitable ratio, it can not only achieve the coexistence of high toughness and flame retardancy, but also promote processing safety and environmental friendliness compared with powdered red phosphorus.
As for the mechanical properties, such as tensile strength, impact toughness, ductility, etc., the red phosphorus masterbatch is slightly hindered. Its essence is an inorganic filler, and if the dispersion is insufficient, it will form agglomeration, resulting in stress concentration and brittle cracking of the material body. Or due to uneven particle size, the interface between the substrate and the filler will be affected, and the strength will gradually lose over time. In addition, if the red phosphorus content is too much, or if it is not added properly, it is easy to cause the melt fluidity to decrease, the process is difficult to form, and the surface is rough. However, if the dosage is appropriate, and it is supplemented with the compatibility agent, dispersant and other additives, it can help it to distribute evenly and reduce the adverse effects, so as to achieve the effect of both performance and flame ret
Red phosphorus is more stable and easier to store than white phosphorus, but its chemical properties still have the disadvantage of high activity. Moisture or high temperature environment, or the formation of phosphoric acid, it is easy to cause the product to be brittle. In actual production, moisture-proof sealing is always required, and coated red phosphorus masterbatch should be selected to shield external influences and prolong the life of the product.
Overall, if the polypropylene red phosphorus masterbatch is mixed by scientific process and used moderately, the flame retardancy will be greatly increased, and the deterioration of physical properties can also be controlled. However, if details such as dispersion and compatibility are ignored, the mechanical properties may be reduced, which cannot be taken lightly. In summary, reasonable selection of masterbatch varieties and optimization of formulation process can make polypropylene products have both excellent flame retardant and usable physical properties, which is conducive to a wide range of industrial applications.
The red phosphorus masterbatch is mixed with the polypropylene masterbatch to obtain its uniform dispersion, which is of great benefit to the flame retardant performance. When the red phosphorus is exposed to high temperature, phosphoric acid is precipitated, covering the burning surface to isolate oxygen and slow down the combustion rate. Mixed in a suitable ratio, it can not only achieve the coexistence of high toughness and flame retardancy, but also promote processing safety and environmental friendliness compared with powdered red phosphorus.
As for the mechanical properties, such as tensile strength, impact toughness, ductility, etc., the red phosphorus masterbatch is slightly hindered. Its essence is an inorganic filler, and if the dispersion is insufficient, it will form agglomeration, resulting in stress concentration and brittle cracking of the material body. Or due to uneven particle size, the interface between the substrate and the filler will be affected, and the strength will gradually lose over time. In addition, if the red phosphorus content is too much, or if it is not added properly, it is easy to cause the melt fluidity to decrease, the process is difficult to form, and the surface is rough. However, if the dosage is appropriate, and it is supplemented with the compatibility agent, dispersant and other additives, it can help it to distribute evenly and reduce the adverse effects, so as to achieve the effect of both performance and flame ret
Red phosphorus is more stable and easier to store than white phosphorus, but its chemical properties still have the disadvantage of high activity. Moisture or high temperature environment, or the formation of phosphoric acid, it is easy to cause the product to be brittle. In actual production, moisture-proof sealing is always required, and coated red phosphorus masterbatch should be selected to shield external influences and prolong the life of the product.
Overall, if the polypropylene red phosphorus masterbatch is mixed by scientific process and used moderately, the flame retardancy will be greatly increased, and the deterioration of physical properties can also be controlled. However, if details such as dispersion and compatibility are ignored, the mechanical properties may be reduced, which cannot be taken lightly. In summary, reasonable selection of masterbatch varieties and optimization of formulation process can make polypropylene products have both excellent flame retardant and usable physical properties, which is conducive to a wide range of industrial applications.
