Flame retardant coverage

Oct 31, 2019

After the flame retardant is added to the combustible material, the flame retardant can form a glass-like or stable foam coating layer at high temperature to isolate oxygen, and has the functions of heat insulation, oxygen barrier, and preventing the combustible gas from escaping outward, thereby achieving flame retardant. purpose. For example, when the organic phosphorus-blocking flame retardant is heated, it can produce a crosslinked solid substance or a carbonized layer which is more stable in structure. The formation of the carbonized layer on the one hand prevents the polymer from further pyrolysis, and on the other hand prevents the internal thermal decomposition products from entering the gas phase to participate in the combustion process.
