Tetraphenyl dipropyleneglycol diphosphite

CAS-nr: 80584-85-6

Molecuulgewicht: 566

Application Instructions

A high-phosphorus content arylalkane phosphite ester antioxidant, widely used in polyurethane, resin synthesis, PVC, ABS and other fields, can provide excellent thermal stability and color improvement. As an efficient auxiliary stabilizer and chelating agent, it is used in both rigid and flexible PVC materials to provide brighter and more uniform colors, increase transparency, and enhance the thermal stability of PVC. It can enhance the thermal stability and long-term stability of polyurethane products. During the polyurethane foaming process, it can effectively alleviate the core burning problem caused by high temperatures and has a good inhibitory effect on phenolic yellowing and NOX yellowing of polyurethane products. Suggested addition amount: 0.1-2.0%
