HF-902K is a halogen-free environmentally friendly flame retardant based on Ammonium
Polyphosphate, fully meet the requirements of RoHS and REACH regulations. This flame retardant is
specially designed for various flame-retardant polypropylene products and can also be used for other
polyolefin flame-retardant products. It is composed of acid source, gas source, and carbon source, with
phosphorus and nitrogen as flame retardant elements, and forms an expanded carbon layer to block oxygen
and fire sources to play a flame retardant role. The flame retardant grade of polypropylene flame - retarded
by HF-902 K can reach UL94 V-0 (1.5mm ) , GWIT 750 ℃, GWFI 960 ℃ , and the flame retardant products
have low density, low smoke and low toxicity , and low corrosion to molds. HF-902K does not contain anti
