Flame retardant include halogenated flame retardant and halogen-free flame retardant.

Novel intumescent flame retardant (TPA) was prepared, and halogen-free retardant ABS composites were prepared by microencapsulated red phosphorus (MRP) and TPA as flame retardants.

Composition and irradiation crosslinking products processing technology of low smoke, halogen free, flame retardant and low temperature heat shrinkable polyethylene were studied.
