Polyrocks Chemical 168S Polypropylene, halogen-free flame retardant
Categories:	Polymer; Thermoplastic; Polypropylene (PP); Polypropylene, Flame Retardant
Material Notes:	168S is low halogen flame retardant environmental polypropylene with phosphorus, bromine and antimony as the flame retardant elements. Through solidifying phase and gas-phase mechanism improve flame retardant performance, and accelerating melting and dripping by catalytic mechanism to play flame retardant performance. 168S flammability can reach UL 94 V-2(1.5mm and 3.0mm),glow-wire test meets GWIT:775/3.0 and GWFI:850/3.0?168S has passed UL certification,and meet the requirements of RoHS?SVHC?PFOS & PFOA?16P?PAHs...etc. 168S has characteristics of finished products low density?low smokes?less corrosion to molds...etc. Information provided by Polyrocks
