Compound Flame Retardant APP Ammonium Polyphosphate For Polypropylene

Compound Flame Retardant APP Ammonium Polyphosphate For Fire Retardant Polypropylene​

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). Polyolefin is the most widely used polymer and has a wide range of applications in all industries. In various consumer-centric industries, the use of polyethylene and polypropylene is increasing. 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.

TF-241 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% dosage TF-241 can pass the tests of UL94 V-0(3.0mm) and GWIT 960℃.

Reference Formula (UL94 V0):

Advantages

1. Low density, low smoke generation.

2. Good water resistance.
3. Halogen-free and none heavy metal ions

Application

TF-241 is used in homopolymerization PP-H and copolymerization PP-B .

It is widely used in flame retardant polyolefin like steam air heater and household appliances.
