Hydrolytically Stable Phosphite Processing Stabilizer
PRODUCT INFORMATION
Characterization
TSH-168 is a hydrolytically stable phosphite processing stabilizer. As a secondary antioxidant, TSH-168 reacts during processing with hydroperoxides formed by autoxidation of polymers preventing process induced degradation and extending the performance of primary antioxidants.
Applications
The application range of TSH-168 -synergistically combined with other Ciba anti-oxidants – comprises polyolefins and olefin-copolymers such as polyethylene (e.g. HDPE, LLDPE), polypropylene, polybutene and ethylene-vinylacetate copolymers as well as polycarbonates and polyamides. The blends can also be used in polyesters, styrene homo- and copolymers, adhesives and natural and synthetic tackifier resins, elastomers such as BR, SEBS, SBS, and other organic substrates. TSH-168 blends can be used in combination with light stabilizers of the TINUVIN and CHIMASSORB range.

Guidelines for use
Typically 500 – 2000 ppm of TSH-168 combined with appropriate levels of other additives are used for the processing stabilization of polymers. The optimum level is application specific. Extensive performance data of TSH-168 combinations in various organic polymers and applications are available upon request.
Handling & Safety
In accordance with good industrial practice, handle with care and prevent contamination of the environment. Avoid dust formation and ignition sources.
