is a low-halogen and environmentally friendly polypropylene flame retardant with a compound synergistic effect of nitrogen, phosphorus and bromin. It requires a small addition amount, does not precipitate, does not need the synergistic effect of Sb203, has a low bromin content, and is suitable for mineral small-scale filling systems. Flame-retardant products have low density, low smoke emission, low mold corrosiveness, and can reach UL94V-2(1.6mm) level with a small amount of addition. They have passed the hot wire test GWIT750ºC and GWFI850ºC tests. What makes it special is that it has excellent aging resistance and is an ideal, efficient and environmentally friendly flame retardant.
