Everfos 168

Everfos 168 is a hydrolytically stable phosphite processing stabilizer as a secondary antioxidant. It reacts during processing with hydroperoxides formed by autoxidation of polymers preventing process induced degradation. EVERFOS-168 reacts with hydroperoxides to yield non-radical products, therefore called hydroperoxide decomposer. EVERFOS-168 is synergistically combined with other primary antioxidant such as EVERNOX-10 and EVERNOX-76 for applied used in polyolefins or olefin-copolymers such as HDPE, LLDPE, PP, EVA as well as PC, PA. The blends can also be used in engineering plastics such as PBT, PET, and styrenics, elastomers like PS, ABS, BR, SBS and tickifier resins, adhesives. EVERFOS-168 protects polymers which are prone to oxidation during processing steps (compounding, pelletizing, fabrication and recycling) from molecular weight change (e.g. chain scission of PP, crosslinking of PE) and prevent discoloration.
