PVC & plastics
Supports initial color and processing stability in selected stabilizer packages.

PHOSPHITE ESTER · CAS 101-02-0
TPP · Phosphorous acid, triphenyl ester
A secondary antioxidant, processing stabilizer and chemical intermediate for selected polymer, resin and synthesis applications.
PRODUCT OVERVIEW
Triphenyl Phosphite can reinforce primary antioxidant systems and support color and processing stability when correctly formulated.
Phosphite esters decompose hydroperoxide intermediates formed during polymer processing. Commercial suitability depends on the resin system, process temperature, additive package, regulatory status and end-use requirements.
Application information supports commercial discussion and does not replace formulation validation. Customers should confirm suitability in their own process.
CHEMICAL IDENTITY
Use the current approved specification, TDS and SDS as the final basis for purchasing, handling and use.
