Product Introduction:
Aluminum hydroxide, also known as hydrated alumina, is a halogen-free environmental flame retardant, which can not only flame retardant, but also can suppress smoke, do not produce droplets and toxic gas, and cheaper than halogenated, phosphorus and other systems, is the most widely used inorganic flame retardant. The company produces aluminum hydroxide flame retardant with ultra-fine, high purity, white, uniform particle size distribution characteristics; After the advanced surface treatment technology, it has good compatibility with the polymer material, and can greatly reduce the impact on the physical and mechanical properties of the material when added in large quantities.
Mechanism of flame retardant
When the flame retardant is heated to a certain degree, it begins to dehydrate, absorb heat and vaporize to produce H2O, thus reducing the temperature of combustible and diluting the concentration of combustible vaporizers and combustion-supporting gases. Meanwhile, an oxide isolation layer is formed on the surface of combustible, thus achieving the purpose of combustible flame retardancy.
