In order to increase the flame resistance of polymer materials, it is mainly used for polymer materials such as plastics, rubber, fibers, etc., most of these materials are combustible. Especially for plastics, if it is to be used in transportation, construction, electrical equipment, aviation, space flight, etc., it is urgent to solve the problem of its resistance to combustion.

Generally, the following conditions should be met: do reduce the physical properties of polymer materials, such as heat resistance, mechanical strength, electrical properties; the decomposition temperature should be too high, but it cannot be decomposed at the processing temperature; good durability; good weather resistance ; Cheap.

When adding PP flame retardant, you must ensure that your raw material is pure PP, otherwise the reaction of PE PP will make the product have poor flame retardant effect, even flame retardant.

PP is an extremely flammable material with a limiting oxygen index of only 17.5, a char formation rate of almost 0, it is easy to melt drip. As people's awareness of fire protection is gradually increasing, the addition of polypropylene flame retardants is very necessary.
