FR601 polyolefin compound halogen-free flame retardant
FR601 is a compound halogen-free expansion flame retardant that does not contain ammonium polyphosphate, which fully meets the requirements of the EU RoHS environmental protection directive and relevant domestic policies and regulations for halogen-free, low smoke and green environmental protection of flame retardant materials. Applied to PP materials, adding less than 22% can reach 1.6mm V-0; The PP material can be filled with talc powder and glass fiber. Compared with bromoantimonic flame retardants, they have the advantages of not corroding mold during extrusion, low price and high flame retarding efficiency.
