Description
Triphenyl phosphite (CAS 101-02-0) is a phosphorus-based organic compound supplied under trade names including JP 360, Mellite 310, Advance TPP, and IRGAFOS TPP. It carries no assigned E-code and is classified under organometallic compounds with HS code 29209085.
In plastics and polymer processing, triphenyl phosphite functions as a secondary antioxidant by decomposing hydroperoxides before they initiate chain degradation, extending service life in polyolefins and engineering resins. In lubricant and rubber formulations, it acts as a stabilizer and mild plasticizer, reducing oxidative breakdown under thermal stress during compounding and service.
Triphenyl phosphite is available in technical and industrial grades, supplied as a liquid in drums or IBC containers. It is subject to REACH registration requirements within the EU. Buyers should confirm grade specifications and SDS documentation prior to procurement to ensure compliance with applicable processing and end-use standards.
