Diisodecylphenyl phosphite
Diisodecylphenyl phosphite (CAS: 25550-98-5) is a specialized organophosphorus compound with the linear formula (C10H21O)2POC6H5 and a molecular weight of 438.62 g/mol. It functions primarily as a highly effective heat stabilizer for various polymer systems. Its chemical properties make it valuable in applications requiring enhanced thermal resistance during processing and end-use, contributing to the longevity and performance of polymeric materials.
Polymer Heat Stabilizer
Diisodecylphenyl phosphite is widely employed as a secondary heat stabilizer in polymers. It works synergistically with primary stabilizers to protect materials from degradation caused by high processing temperatures and long-term heat exposure.
PVC Stabilization
It is particularly effective in stabilizing polyvinyl chloride (PVC) formulations, preventing dehydrochlorination and discoloration during extrusion, moulding, and other high-temperature processing steps.
Polyolefin Additive
This phosphite ester can be incorporated into polyolefins like polyethylene and polypropylene to improve their thermal oxidative stability, thereby extending their service life in demanding applications.
