[Typical Properties]

Soluble in organic solvents, insoluble in water.

[Specification]

[Usage]

A high phosphorus content arylalkyl phosphite antioxidant widely used in polyurethane, resin synthesis, PVC, ABS and other fields, which can provide excellent thermal stability and color improvement. As an efficient auxiliary stabilizer and chelating agent used in hard and soft PVC materials, it provides brighter and more uniform colors, increases transparency, and improves the thermal stability of PVC. It can improve the thermal stability and long-term stability of polyurethane products, effectively improve the burning problem caused by high temperature during the polyurethane foaming process, and have a good inhibitory effect on the yellowing of phenol and gas smoke (NOX) in polyurethane products. Suggested addition amount: 0.1~2.0%
