Product Description



18µm Low Density APP Halogen Free Flame Retardant Additives for PP

PP Flame Retardant APP Ammonium Polyphosphate Based Compound Halogen Free Flame Retardant


Today, the global demand for flame retardants has exceeded 2 million tons per year. The main part of this demand comes from the global plastics industry. Because all carbon-based materials are flammable and plastics are so widely used, it is necessary to reduce the risk of fire-related accidents.

Halogen-free flame retardants can be used in all types of polymers in electronics, construction, automotive and other industries. Polyolefin applications are expected to be the main field, followed by epoxy resins and unsaturated polyesters (UPE).

Polyethylene and polypropylene are the most widely used polymers. When these polymers are mixed with halogen-free flame retardants, they are mainly used for packaging, wires and cables, circuit boards, and various other uses for maintaining fire resistance. The booming electronics and automotive industries will catalyze the demand for halogen-free flame retardants for epoxy resins.


TF-241 mainly contains P and N, is a kind of halogen-free eco-friendly compound flame retardant for polyolefin. It has been developed especially for various PP. Containing acid source, gas source and carbon source, TF-241 takes effect by char formation and intumescent mechanism. PP with 22% TF-241 can pass the tests of UL94 V-0(3.0mm) and GWIT 960℃.
