PP fireproof accessory ingredient
The nanoscale flame-retardant masterbatch additive has good processing liquidity and excellent heat stability and photostability , and can reach excellent flame-retardant effect without adding antimonous oxide and directly inject products after mixing with PP and PE plastic. Because of nanoscale fineness, it overcomes the defects of high density and large addition cost, seriously deteriorated physical properties, poor compatibility with resin, easy -precipitation, frosting and whitening due to large additive amount of conventional fire retardant.so it is the first choice of flame-retardant products . In full compliance with EU environmental protection standard RoHS, the product is free of PBB or PBDE.
