Low halogen flame retardant PP master batches based on phosphorus, nitrogen and bromine as main flame retardant elements. It improves flame retardant efficiency by synergistic effect of solidifying phase and gas-phase mechanism, and accelerating melting and dripping by catalytic mechanism to play flame retardant performance. It is used for adding to pp to reach UL94 V2 flammability grade, adding a certain percentage of master batches in homopolymer PP ( or mixture of homopolymer pp and copolymer pp), could reach excellent flame retardant effect. It has UL certification, and meets the requirements of RoHS?SVHC?PFOS & PFOA?16P?PAHs...etc. 5003RM has the properties of low density, low smoke, less corrosion to moulds.Information provided by Polyrocks |
