Phosphate Flame Retardants
- Product
- Triphenyl Phosphite (TPPI)
Overview
Triphenyl phosphite (TPPI) is a colorless to light yellow liquid that may solidify below about 22 ℃. It is an important secondary antioxidant and heat stabilizer for plastics and an intermediate for other phosphites.
Also known as
TPPI; Phosphorous acid triphenyl ester; Triphenoxyphosphine
