    What is the heat resistance of FR Ammonium Polyphosphate Mflam AP231?
    Ammonium Polyphosphate, whose name is Mflam AP231, is widely used as a flame retardant, especially in polymer materials. Its properties are observed, but heat resistance is preferred. This product is polymeric ammonium phosphate, with stable chemical properties, chain-like structure, and strong molecular association, so it has remarkable high temperature resistance. Usually, between 200 and 300 degrees Celsius, it gradually decomposes and releases ammonia gas, which reacts with polymer materials to form a dense carbon layer, which not only cuts off the supply of fuel gas, but also prevents heat from penetrating, which is the reason for flame retardants.
    Examining its thermogravimetric curve, it can be seen that its initial decomposition temperature is more than 200 degrees Celsius, or even more than 270 degrees Celsius, which is better than a class of oligomeric products; stored at room temperature, there is no obvious decomposition or migration, and it will not interact with other additives. It has good stability for plastics, rubber, fibers and other substrates. Its melting point is slightly higher, and it gradually softens at high temperature, but it is not easy to spontaneously ignite, and it is not a heat source itself. In the processing process, it can withstand the conventional conditions of general thermoplastic materials, and is especially suitable for extrusion, injection molding and other links to avoid aging and deterioration.
    However, if the temperature exceeds the limit, it will eventually be difficult to stop thermal degradation. If it is too high, it will release gas. If it encounters strong acid and alkali, it will also be worried about falling apart. However, its thermal stability is several times better than that of A-type and oligomeric ammonium phosphate. Experiments show that below 300 degrees, the decomposition rate is very low, and the carbonization effect is increased, which can greatly delay the spread of fire. In the addition of flame retardant system, it has both chemical stability and thermal stability, which helps the product to serve under slightly higher working conditions and can prolong the service life.
    Overall, the heat resistance of Mflam AP231 is not only suitable for a variety of high-temperature compounds, but also provides a solid barrier for various engineering plastics.

Secondly, phenolic resins can also be compatible with it. Phenolic has some flame retardant properties. Ammonium polyphosphate participates in the pyrolysis process and synergistically enhances the flame resistance of the material.
    As for thermoplastic resins, polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), halogen-free flame retardant polystyrene (HIPS), polyester (such as PET, PBT), etc., can be blended with Mflam AP231 in an appropriate proportion. Its effect is particularly remarkable in polypropylene systems. It often forms a synergistic flame retardant system with melamine, polyols, etc., through expansion and carbonization, blocking the contact between the heat source and oxygen. If matched with suitable dispersants and capacitors, it can be evenly dispersed in polyethylene and polyester to avoid performance degradation. PVC resin can also be added directly to enhance its expansion flame retardancy and reduce the generation of harmful gases.
    In addition, Mflam AP231 can also be competent in water-based acrylic resins and polyurethane systems. In water-based coatings, adhesives and other products, it can not only maintain transparency and mechanical properties, but also greatly improve the fire rating.
    However, when it is compatible with some high-polarity and strong reducing resins, the formula design must be carefully considered to prevent chemical reactions from affecting the durability. Only new technologies such as surface coating or microencapsulation can expand its application field and improve compatibility with new resins.
    Overall, Mflam AP231 is highly compatible with most thermosetting, thermoplastic, and some water-based resins, and can be widely used in plastics, coatings, fibers, adhesives, and other fields. It is a good choice for flame retardant materials.
