Antioxidant 168 CAS NO 31570-04-4

As a secondary antioxidant,it can be synergistically combined with other antioxidants such as antioxidant 1010(CAS NO.:6683-19-8).the combination of antioxidants provide storage stability and give the polymer long term protection against thermo-oxidative degradation.the blends can be used in polyolefins and olefin-copolymers such as polyethylene(such as HDPE,LLDPE), polypropylene,polybutene and ethylene-vinylacetate copolymers, polycarbonates, polyamides, polyesters,styrene homo- and copolymers,adhesives and natural and synthetic tackifier resins, elastomers such as BR, SEBS, SBS and other organic substrates. The antioxidants blends can be used together with other light stabilizer to provide polymers better stability.

Applications:

1.As a secondary antioxidant,it can be synergistically combined with other antioxidants such as antioxidant 1010(CAS NO.:6683-19-8).the combination of antioxidants provide storage stability and give the polymer long term protection against thermo-oxidative degradation.the blends can be used in polyolefins and olefin-copolymers such as polyethylene(such as HDPE,LLDPE), polypropylene,polybutene and ethylene-vinylacetate copolymers, polycarbonates, polyamides, polyesters,styrene homo- and copolymers,adhesives and natural and synthetic tackifier resins, elastomers such as BR, SEBS, SBS and other organic substrates. The antioxidants blends can be used together with other light stabilizer to provide polymers better stability.

2.It is an organophosphite 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) form molecular weight change(such as chain scission,crosslinking) and prevent discoloration.
