Historical Development
Since ancient times, technology has advanced, and materials have been replaced. Modern chemistry is in the ascendant, and the need for thermal insulation is particularly evident. The former extruded polystyrene board (XPS) was made, which cut off heat and sound insulation, and was highly respected for the benefit of the people. However, it is flammable in case of fire, and hidden dangers lurk. As a result, all craftsmen have tried their best to seek stability, so they have explored the use of fire retardant additives. The initial use of external coating has little protection. Then scientific research has been carried out one after another to make flame retardant masterbatch, which is coagulated in resin, which is strong inside and strong outside, and its performance has been greatly improved. The formula is new, the process is gradual, and the flame retardant performance has been significantly improved, and its application is also in the fields of construction and cold chain.

Preparation Method
The system of XPS flame retardant masterbatch is made of polystyrene resin as the main material, supplemented by flame retardant, foaming agent, and auxiliary agent. The materials are strictly selected and weighed according to the ratio. First, the resin is melted at high temperature, and the flame retardant and auxiliary agent are added. Mix evenly, and gradually heat up to make the material-liquid fusion ultimate. Then slowly apply the foaming agent, and through airtight high pressure, the gas is uniformly penetrated into the melt. The extruder is rotated, and the pressure is suddenly reduced to cool, and the bubbles are precipitated to form a porous masterbatch. In the reaction, the catalytic mechanism lies in the decomposition of the auxiliary agent to promote the foaming agent, release the gas, make the bubbles fine and uniform, and interact with the flame retardant to improve the stability of the masterbatch and reduce harmful by-products. Masterbatch, uniform particle size, outstanding performance, can give XPS board fire retardant, foaming light effect.
Chemical Reactions & Modifications
Polystyrene foam sheet, in order to enhance its flame retardant properties, commonly used modification technology in production. Mixing flame retardant masterbatch on the matrix, its essence lies in the combination of chemical reaction and physical doping. If bromine or halogen-free flame retardant is the main one, in case of high temperature, it decomposes to generate free radical trapping agent, breaks the chain to suppress smoke and inhibit combustion. Another example is the phosphorus and nitrogen system, which generates an expanded carbon layer during decomposition to isolate oxygen and delay pyrolysis. Further compounding nanomaterials, by means of interfacial chemical reactions, make them uniformly dispersed in the polymeric matrix to improve thermal stability and flame retardancy. Surface coating and coupling agent cooperate to change chemical bond energy and enhance compatibility, so that the flame retardant masterbatch and XPS are firmly combined, and the flame retardant effect is more obvious. In summary, all these are based on the chemical modification of materials and the clever use of reaction mechanisms to achieve excellent performance Foaming XPS Flame Retardant Masterbatch.
Synonyms & Product Names
Synonyms refer to things with different names and refer to the same thing. Foaming XPS Flame Retardant Masterbatch is the western name of polystyrene foam flame retardant masterbatch. Although the names are different, they actually refer to the same thing. They are used in the production of extruded polystyrene sheets to increase their fire resistance. The name is more and more, due to trade, region, and use, but its essence is inseparable from the use of polystyrene foam flame retardant masterbatch.

What are the main ingredients of Foaming XPS Flame Retardant Masterbatch?
Foaming XPS Flame Retardant Masterbatch is a foamed flame retardant masterbatch of extruded polystyrene (XPS). This article describes its main points and examines its ingredients.
It is a industrial material, and the main purpose is to give XPS board good foaming and flame retardant properties. Its substrate is mostly polystyrene resin, which is its body. Refined from petrochemical products, it is strong and light in quality, and can withstand low temperature. For the work of foaming, a foaming agent is often added, or isopentane, or butane, or carbon dioxide. These inert gases are often dissolved by heat and form pores, making it loose in texture and well insulated.
However, XPS board is flammable when exposed to fire, which not only damages safety, but also harms the environment. Special flame retardants are used to control fires, and hexabromocyclododecane (Hexabromocyclododecane, HBCD) is the main one. This material contains bromine, which releases chemical reactions when heated, blocks oxygen, and is dangerous and difficult to burn. Now due to environmental regulations, new environmentally friendly flame retardants (such as ammonium polyphosphate, antimony trioxide supplemented by phosphorus and nitrogen flame retardants, or halogen-free environmentally friendly flame retardants.
In addition to flame retardant and foaming materials, there are additives. Either for lubrication, or for dispersion, so that the raw materials are uniform and easy to mix, and their rheology is adjusted. There are antioxidants to prevent excessive heat transfer and polymer decomposition. Sometimes colorants, antistatic agents, and processing stabilizers are also added to make the performance more complete.
To sum up, the main ingredients of Foaming XPS Flame Retardant Masterbatch are first polystyrene resin, second is foaming agent, which is used to make holes, and both flame retardants to suppress fire, supplemented by various additives to make it complete. Therefore, the need for processing should be met, and the importance of safety and environmental protection should be met. In this world, chemical technology has continuously improved its formulation, inhibited harmful, improved performance, and committed to both foaming, flame retardant and environmentally friendly responsibilities. This is the case with the use of its ingredients.

How does Foaming XPS Flame Retardant Masterbatch affect the flame retardant performance of XPS sheet?
Foaming XPS Flame Retardant Masterbatch refers to the flame retardant masterbatch added in the preparation process of extruded polystyrene sheet (ie XPS sheet). Its body contains special flame retardant components, which can delay the combustion of XPS sheet in case of fire and inhibit the rapid spread of flame. Because XPS is an organic polymer, it is flammable and releases a lot of toxic gases when burning, so there are many safety concerns in construction projects. Today, the introduction of flame retardant masterbatch, in the key stage of foaming mixing and extrusion molding, is evenly blended with the original base material, and both inside and outside are repaired to achieve the effect of flame retardant and increased safety.
Flame retardant masterbatch plays an effect in the plate, mainly in the combination of physical heat insulation and chemical flame suppression. When the core flame retardant encounters high temperature, phosphorus, nitrogen, bromine and other elements are precipitated, which can form a carbonization protective film on the surface of the material, blocking oxygen and heat sources, and greatly retarding heat conduction. At the same time, inert gases are released in the carbon layer, diluting the flammable components of the combustion environment and suppressing the rise of the fire. In addition, some components in the flame retardant system generate free radical interruptors during the pyrolysis process to inhibit the cracking reaction chain of polymers, reduce the precipitation of flammable gases, and slow down the entire combustion process.
In addition, the addition amount and dispersion of flame retardant masterbatch also affect the flame retardant performance of XPS sheets. If the addition is moderate and evenly distributed, it can maintain the dense mechanism of the board, which not only has the effect of flame retardancy, but also does not damage its structure and thermal insulation. If the dosage is improper or the dispersion is not good, the flame retardancy will inevitably reduce the efficiency, and even the advantages of board mechanics and thermal insulation will be damaged, but it will be unfavorable. Therefore, the various process parameters in the preparation process must be finely regulated to make the flame retardant substance and XPS resin integrate and complement each other, which is the best policy.
To sum up, Foaming XPS Flame Retardant Masterbatch has significant functions in improving the flame retardant performance of XPS board. It not only reduces the combustion rate, but also suppresses the generation of harmful flue gas to ensure building safety. The way of application depends on the scientific formulation and fine craftsmanship, so that both flame retardancy and material properties can be taken into account, so that XPS board is in a position of both safety and efficiency.

What is the addition ratio of Foaming XPS Flame Retardant Masterbatch?
Foaming XPS Flame Retardant Masterbatch is a special flame retardant masterbatch for expanded polystyrene insulation boards. This material neutralizes the functions of promoting foaming and flame retardant, and is widely used in the fields of construction and thermal insulation. It is important to cover the proportion of its addition. It is necessary to ensure the flame retardant effect, but also to take into account the foaming performance, and to cost economy. Considering the process practice and related literature, the common addition ratio is about 3% to 8%, but the actual application is still the material review, process, flame retardant standards, etc.
At the beginning, the type and content of flame retardant components of the masterbatch are selected, which directly affects its dosage. If the amount added is too small, the flame retardancy is insufficient, and it is difficult to achieve the B1 flame retardant standard. If there is too much, or the foaming performance is impaired, the bubble structure of the product is not good, and the mechanical strength of the plate is reduced. In view of this, it is necessary to try several times when designing the formula, and the balance between flame retardancy and foaming is the best.
When working, it is advisable to mix the masterbatch with the polystyrene resin first, and the ratio is accurate and the mixture is uniform. Usually, the base number of 5% is adjusted as needed. If it is a general flame retardant requirement, take the lower limit and use 3%; if B1 is required to be highly flame retardant, it can be increased to 6% to 7%, and the extreme requirement may be used to 8%. However, when adding to more than 7%, special attention must be paid to the dispersion of the material to prevent the fluctuation of the performance of the plate.
And the activity of the masterbatch provided by different manufacturers is also different. It is recommended to refer to the product manual first. Process conditions such as temperature and pressure must also be adjusted. In the debugging stage, small batches should be used for trial production, and the proportion should be optimized according to the test data, so as to ensure that the flame retardant, strength and foaming can be used well.
To sum up, the dosage of Foaming XPS Flame Retardant Masterbatch should be determined according to the flame retardant requirements and the characteristics of the masterbatch. 3% -8% is appropriate, and 5% is commonly used for promotion. When developing new products, testing is the way to improve, and fine-tuning with the results can be achieved.

Does Foaming XPS Flame Retardant Masterbatch affect the foaming effect of XPS sheets?
Foaming XPS Flame Retardant Masterbatch is based on the flame retardant masterbatch used in polystyrene foam products. Today, I ask whether this flame retardant masterbatch damages the foaming effect of XPS sheet, and I would like to state it in the text as follows:
Flame retardant masterbatch, which is designed to improve the fire resistance properties of XPS sheet. The main materials are mostly bromine and phosphorus, compounded with dispersants, carriers, etc. However, the foaming process depends on the melting and flow of resin, and then the action of foaming agent to form a closed-cell structure, which is used for lightweight and thermal insulation. The introduction of the masterbatch is beneficial to flame retardancy. However, if its properties are not suitable for the resin, or its distribution is uneven, it will inevitably cause changes in melt viscosity, inhibit fluidity, and make it difficult for the foaming agent to be evenly distributed. Finally, the size of the foam cells is very different or the number of connecting holes increases. In this way, the plate is loose, the density is abnormal, and the heat-breaking effect is reduced.
Moreover, if the masterbatch formula contains inorganic fillers, or the particle size is large, it is easy to be a nucleation point and cause clutter in the foam cells. Brominated flame retardants, when foamed at high temperatures or precipitate decomposition products, these products may chemically interact with polystyrene to improve the properties of the resin. If the amount of masterbatch is very high, it is particularly significant. However, if the choice of high-quality flame retardant masterbatch, the particle size is fine, well dispersed, and compatible with the substrate, then these adverse effects can be significantly reduced. Today's advanced formulas are mostly designed with synergy effect, taking into account flame retardant and foaming, so the effect on the foaming effect of the plate is gradually weak.
In general, if the process is improper, the main distribution is not harmonious, and the flame retardant masterbatch may inherently affect the homogeneity of the plate foam, the closure of the bubble and the uniformity of the density. To achieve both foaming and flame retardant beauty, it is necessary to use a fine process to cooperate with the appropriate masterbatch, carefully select the raw materials, and strictly control the dosage to ensure both. If this is the case, the Foaming XPS Flame Retardant Masterbatch has little loss of foaming effect, and can improve the safety performance of the product.
In summary, although the application of flame retardant masterbatch can have a certain impact on foaming, it can be made invisible through process optimization and material selection. Foaming and flame retardant go hand in hand, and it is also necessary.

It must be stored and transported carefully to ensure that its properties remain unchanged, the quality is not damaged, and disasters are avoided. The cover contains many flammable ingredients, and the performance will be inaccurate when heated. If it is not properly disposed of, there may be hidden dangers. Therefore, it is advisable to follow the rules and be careful, and everything should be detailed.
At the beginning, it should be stored in a dry and ventilated room, and it should not be mixed with water vapor and moisture. The room has a moderate temperature, away from the high temperature of the fire source. It should also be placed in a cool and dark place, protected from exposure to the sun, and do not steam and bake at high temperature. When stacking, it should be scattered, and avoid heavy pressure to prevent objects from being deformed or scattered. The packaging should be intact and must not be broken to prevent foreign matter from infiltrating and affecting its performance. Regular inspections should be made to prevent rodents and insects from biting and cutting.
Transportation should be cautious. Check that the packaging is firm first to eliminate the risk of damage. It should also be marked with words such as "flammable" and "moisture-proof" to warn the person handling it. During transportation, it should be prohibited to rush and drop, and handle it lightly. It should not be loaded and juxtaposed with strong acids, strong alkalis, volatile solutions and harmful odors to avoid reactions. If transported over long distances, the vehicles used should be protected and waterproof to avoid rain and sun exposure. Temperature should be controlled in winter and summer, and it is not suitable for drastic changes in temperature difference. If there is any danger on the way, it should be isolated immediately to avoid the spread of the disaster.
The warehousing and transportation links must be managed by special personnel, trained, and aware of the operating procedures. If any abnormalities are found, they must be reported quickly and cannot be neglected. Regularly check the inventory, make sure that the accounts are in line, and prevent the accumulation from expiring, so as to ensure the quality.
To sum up, the method of storage and transportation must be careful, fire prevention, moisture prevention, and pollution prevention, to ensure the safety and cleanliness of the storage environment. In this way, the Foaming XPS Flame Retardant Masterbatch must be stored and used for a long time, without fear of quality damage.

Regular inspections should be made to prevent rodents and insects from biting and cutting.
Transportation should be cautious. Check that the packaging is firm first to eliminate the risk of damage. It should also be marked with words such as "flammable" and "moisture-proof" to warn the person handling it. During transportation, it should be prohibited to rush and drop, and handle it lightly. It should not be loaded and juxtaposed with strong acids, strong alkalis, volatile solutions and harmful odors to avoid reactions. If transported over long distances, the vehicles used should be protected and waterproof to avoid rain and sun exposure. Temperature should be controlled in winter and summer, and it is not suitable for drastic changes in temperature difference. If there is any danger on the way, it should be isolated immediately to avoid the spread of the disaster.
The warehousing and transportation links must be managed by special personnel, trained, and aware of the operating procedures. If any abnormalities are found, they must be reported quickly and cannot be neglected. Regularly check the inventory, make sure that the accounts are in line, and prevent the accumulation from expiring, so as to ensure the quality.
To sum up, the method of storage and transportation must be careful, fire prevention, moisture prevention, and pollution prevention, to ensure the safety and cleanliness of the storage environment. In this way, the Foaming XPS Flame Retardant Masterbatch must be stored and used for a long time, without fear of quality damage.
