Triphenyl Phosphite CAS 101-02-0 | High Purity TPPi Manufacturer & Supplier
Product Name: Triphenyl Phosphite
CAS Number: 101-02-0
Other Names: Triphenyl Phosphate, TPPi
Product Description
Triphenyl phosphite (TPPi) is an important organophosphorus compound, appearing as a colorless to light yellow, transparent liquid with a slight aromatic odor. It is not only a highly effective antioxidant and stabilizer, but is also widely used as a processing aid for polymer materials such as PVC, polyolefins, and rubber, significantly improving their thermal stability, aging resistance, and gloss.
In the fine chemical industry, TPPi is also used as an intermediate in chemical reactions such as esterification, polycondensation, and addition. It is widely used in formulations for lubricant additives, coatings, and preservatives.
