1.Secondary Antioxidant For Polyolefins And Styrenics: Triphenyl phosphite (CAS 101-02-0) works as a secondary antioxidant in polymer stabilisation, protecting polyolefins, styrene copolymers and rubber from thermal and oxidative degradation during processing.
2.PVC Heat Costabiliser: Used as a heat costabiliser in PVC, it supports the stabiliser system that keeps vinyl compounds from degrading during high temperature processing and forming colour.
3.Colour And Photostability: Applied in PVC, polypropylene and polystyrene it helps maintain the photostability of the finished polymer and improves the colour of the processed resin.
4.Polymerisation Stabiliser For Vinyl Chloride: In polymerisation systems it acts as a stabiliser and antioxidant during the polymerisation of vinyl chloride and other monomers, helping keep the reaction medium under control.
5.Intermediate For Phosphite And Organophosphorus Chemistry: The ester serves as an intermediate for preparing other phosphite esters and as a phosphorus source and ligand in the synthesis of transition metal phosphide nanoparticles.
