Omnistab AN 168

Omnistab AN 168 is a hydrolytically stable phosphite processing stabilizer. Also acts as an antioxidant. It has low volatility and is particularly resistant to hydrolysis. Provides storage stability and give the polymer long term protection against thermo-oxidative degradation. It protects polymers which are prone to oxidation, during the processing steps (compounding/pelletizing and recycling) from molecular weight change (by chain scission or crosslinking) and prevents discoloration. Omnistab AN 168 is compatible with polyesters, styrene homo- and copolymers, polyolefins, olefin-copolymers such as (HDPE, LLDPE), polypropylene, polybutene and ethylenevinylacetate copolymers as well as polycarbonates, polyamides and elastomers such as BR, SEBS, SBS, and other organic substrates.
