What are the main ingredients of Economic Halogen Free Flame Retardant for PU Foam?
The main components of this type of flame retardant foam, such as polyurethane foam (PU Foam), are mostly based on the flame retardant raw materials. The ancients said that things have a beginning, things have a beginning, and the development of flame retardant materials must be protected by fire suppression.
Its main components, often including phosphorus-based flame retardants such as polyphosphoric acid and phosphorus, rely on the flame retardant, do not release toxic chemicals, and can be compatible with the foam base. More nitrogen-based flame retardants, such as melamine, decompose into inert materials and fire insulation. In additives, it is also difficult to produce water, such as oxidation and oxidation, which can decompose and release water at high temperatures, reduce the burn rate, and generate fire protection.
Polyphosphoric acid, white powder, in the middle of phosphoric acid, promote foam carbonization, and shield fire. Melamine, white crystals, decompose in liters, nitrogen and amine, flame asphyxiation. Oxidation and oxidation are all white powders, at 180 to 350 degrees Celsius, put crystal water, and have the ability to cool and dilute combustion. These ingredients are used in combination to reduce the flame retardant effect.
In addition to suppression, cross-cutting, dispersion, etc., the amount of small, but can improve the flame retardant foam dispersion, less force and comfort. This also adds flowers to the flame retardant materials.
As mentioned above, the main type of flame retardant material is phosphorus, nitrogen and gold. Take the balance of the cost of protection, benzene and mercury, to help people safety and fire. With the development of the generation, the formula is also increasingly innovative, and the national health and security are safe.
Economic Halogen Free Flame Retardant for PU Foam What types of PU foam are suitable for?
Flame retardant polyurethane foam (PU foam). There are many types of polyurethane foam, which are generally divided into flexible foam and hard foam. Flexible foam has good flexibility and richness, and is often used in furniture, beds, transportation seats, packaging materials and sound insulation materials. Hard foam is solid, and it is widely used in construction, maintenance, cooling, and pipe-coated refrigerators.
Flexible foam first. This PU foam is divided into pores, semi-pores, pores, and other types, all of which have good performance. It is flammable in case of fire and harmful to discharge. The flame retardant resin has good compatibility, but it does not affect the flexibility and durability of the foam. It is suitable for use in seating, household bedding, and sound insulation. It is not only flame retardant, but also protects people from toxin toxicity. It is especially useful for high-quality room use.
Second-time hard foam. This PU foam has high density, large porosity, and low porosity. It is mostly used for building plates, refrigeration, external protection, and pipeline coating. The flame retardant is mostly made of materials containing sulfur, which causes the corrosion to fill up and endanger the safety of humans and animals. Today, it is replaced by a high-grade flame retardant, which can effectively spread the flame, inhibit the generation of toxic chemicals, meet the requirements of color protection, and reduce the cost and performance. It can also be used for high-grade hard foam to improve the fire protection of large surfaces.
In addition, in special applications such as molding foam and filling foam, the high-quality flame retardant foam can be proportionally matched to ensure high-quality flame resistance and no impact on foam products. IKEA equipment, packaging, high-speed roads, aerospace and other fields.
In other words, high-quality flame retardant foam is made of flexible, semi-high-quality, and hard PU foam. It has an important position in the performance of fixed, low-cost, low-cost, low-cost, low-cost, and safety protection.
What is the Standard of Economic Halogen Free Flame Retardant for PU Foam?
The Economic Halogen Free Flame Retardant for PU Foam is a new environmentally friendly polyurethane foam flame retardant. Its main purpose is to reduce combustion risk, improve material safety, and balance economy and ecology. Its flame retardant effect is often measured by a variety of international standards, especially UL 94, CA TB117, ISO 11925-2 and GB 8624. UL 94 is the flammability test of plastic materials in the United States, which is common in the industry. Its grades are V-0, V-1, and V-2. Economic Halogen Free Flame Retardant can often help PU foam reach V-0 or V-1 grades, which is manifested as the flame self-extinguishes within a specified time and does not drip combustion materials, preventing the spread of fire.
Another example is CA TB117, which is a California flame retardant test for PU foam for soft furniture. It requires that the material must not continue to burn under the action of a small fire source (such as cigarettes). After the application of this flame retardant, the PU foam can pass the test smoothly, and the flame will extinguish itself after contact without obvious carbonization or damage. As for the ISO 11925-2 test commonly used in Europe, the PU foam is ignited vertically with a small fire source of matches to observe the flame height and spread speed. The flame must not exceed the specified height and there is no continuous combustion phenomenon. The PU foam equipped with Economic Halogen Free Flame Retardant can also meet this standard, which is difficult to support combustion and is not easy to spread.
China's GB 8624 is the classification standard for the combustion performance of building materials. After the flame retardant is used in PU foam, it can be up to B1 level, that is, it is not flammable, and it will self-extinguish in case of short-term combustion in an open flame. It is this kind of flame retardant, which does not use halogens, reduces the generation of harmful gases, and is environmentally friendly. It is widely used in furniture, automobiles, buildings and other occasions that require flame retardancy.
In summary, this flame retardant is used in PU foam and can meet international and domestic mainstream flame retardant standards such as UL 94 V-0/V-1, CA TB117, ISO 11925-2 and GB 8624 B1. It is manifested as flame self-extinguishing, dripping does not continue to ignite, fire does not Contemporary demands for green manufacturing are all beneficial.
Does Economic Halogen Free Flame Retardant for PU Foam affect the physical properties of PU Foam during use?
Halogen Free Flame Retardant is used in PU foam, which is the green and environmentally friendly choice of the world. It aims to slow down the fire and ensure safety. However, how can the properties of things be easier? It is consulted by many craftsmen and bachelors from time to time: If this halogen-free flame retardant is mixed with PU foam, will its physical properties be damaged?
PU foam, originally known for its light, soft and excellent elasticity, is widely used in bedding, packaging, and thermal insulation industries. The entry of flame retardants is to suppress its flammability and make it safer. However, when materials are mixed, they will inevitably interact with each other; flame retardants may be halogen-free, but their essence is mostly phosphorus, nitrogen, or inorganic compounds. The mechanism may contain fire by methods such as heat absorption, gas release, and charcoal formation, but at the same time, it may also cause slight changes in the foam structure.
Considering the experiments and literature, the addition of flame retardants, if the amount is moderate, the density, elasticity, tear resistance and other properties of PU foam are slightly difficult, but they can be tolerated. If the amount exceeds the limit, the pores may be uneven, the density is slightly increased, the elasticity is slightly reduced, and the flexibility is also reduced to the prime state. The reason is that the flame retardant is mixed in the resin, which hinders the extension of the chain segment, and the foam formation is not natural. Therefore, the mechanical properties such as resilience and compression deformation are all slightly different. However, there are skilled craftsmen who use nanotechnology and surface modification methods to adjust the compatibility, which can make the flame retardant and foam blend, and try to maintain the authenticity of the performance as much as possible. In summary, the proper use of halogen-free flame retardants has limited impact on PU foam, which is generally harmless. If its dosage is appropriate, the formula is appropriate, and the process is refined, the physical properties will be reduced very little. However, if the dosage is too much, or the process is improper, the performance may be affected, which cannot be ignored. Today, we advocate green safety, take halogen-free as the right way, and it is advisable to mix carefully and refine the process to make new materials safe and good, for the benefit of all the world.
Is Economic Halogen Free Flame Retardant for PU Foam certified for environmental protection?
Economic Halogen Free Flame Retardant for PU Foam is also a halogen-free flame retardant used in polyurethane foam. Today, if you ask whether it has passed the relevant environmental protection certification, you can state the following according to the facts.
Flame retardants were originally born to reduce fire hazards, but in the past some flame retardants contained more halogens, which were easy to release harmful substances when burned, and the damage exceeded the benefit. Later chemists deeply observed its disadvantages and developed halogen-free flame retardants. Such materials take both safety and environmental protection into account. Economic Halogen Free Flame Retardant, as the name suggests, is both harmful to halogen removal and economical. The international community is increasingly stringent in environmental protection regulations. The European Union has REACH regulations, ROHS directives, US states may have more detailed rules, and China also implements GB and HJ standards. If you want to pass in the market, halogen-free flame retardants should be tested and certified, including but not limited to SGS, UL, ISO14001, ISO9001, REACH SVHC testing, ROHS testing, or China environmental labeling and other certifications.
Certified Economic Halogen Free Flame Retardant is mostly based on halogen-free components such as phosphorus, nitrogen, silicon, etc. The testing items cover VOC (volatile organic compounds) release, heavy metal content, and whether harmful substances exceed the standard. By practicing these methods, their products have been awarded the title of green products and are widely used in Europe, America, Asia and Africa. Otherwise, it shall not be listed in the green procurement catalogue of the mainstream market. However, the specific products produced by a certain manufacturer still need to check whether they have the above certification list. Most of the promotional materials, packaging labels, publicity instructions or contract materials of regular manufacturers will contain the certification document number of the product, stating that it has passed the REACH, ROHS, VOC and other tests and meets international environmental protection requirements. If not, users should be careful to verify.
In short, Economic Halogen Free Flame Retardant for PU Foam can be called a green material if it meets and passes the international and domestic environmental protection certifications such as ROHS and REACH, and it is used in polyurethane foam products. However, the evidence must be checked in detail to avoid misbelieving rumors or business boasts. In this way, it is not only beneficial to ecological safety, but also in line with social responsibility.
