Applications
PUREfos 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. PUREfos 168 reacts with hydroperoxides to yield non-radical products, therefore called hydroperoxide decomposer. Purefos-168 is synergistically combined with other primary antioxidant such as Purestab-1010 and Purestab-1076 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. Purefos-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, cross linking of PE) and prevent discoloration.

Features and benefits
PUREfos 168 is an organophosphate of low volatility and is particularly resistant to hydrolysis. It protects polymers which are prone to oxidation, during the processing steps (Compounding/pelletizing, fabrication and recycling) from molecular weight change (e.g. chain scission/cross linking) and prevent discoloration. Purefos-168 performs best when combined with other Polygel antioxidants.

Guidelines for Use
Recommended loading concentrations range between .0.05% and 0.2 % combined with appropriate levels of other additives are used for the processing stabilization of polymers. The optimum level is application specific.

Storage
This product may be stored up to two years in a sealed container. Containers should be kept tightly closed when not in use and stored in a cool, dry place.
