Product Description

China professional manufacture PP Flame Retardant


      FR-1420 is especially designed for polypropylene, polyethylene and other advanced polyolefin products. FR-1420 contains acid source, gas source and carbon source, taking flame retardancy effect by intumescent flame retarded mechanism.
        Flame retarded by FR-1420, polyolefin and glass fiber reinforced polyolefin can reach UL 94 V-0 (1.5mm) and pass Glow Wire test of GWIT 900℃ and GWFI 960℃.and it is free from the restrictions of RoHS Directive 2002/95/EC approved by the EU and the Council. The products with FR-1420 are characterized by low density, good thermal stability, high flame retarded efficiency, low smoke generation and less mold corrosion. Polyolefin with FR-1420 will not lead to the phenomenon of water-sliding surface during the process of extrusion due to its ammonium polyphosphate free system.FR-1420 doesn’t contain anti-dripping agent.
