CAS No 3050-88-2
Formula C45H69O3P
Application

Colorless or light yellow transparent viscous liquid

Non-polluting heat-resistant antioxidant antioxidant.

It is suitable for rubber and plastic elastomers such as SBS, TPR, IPS, PS, SBR, BR, PVC, PE, PP, ABS, etc. It has high thermo-oxidative stability and does not change color during processing and use. It is especially suitable as a non-discoloring stabilizer.

It has no effect on the color of the product, and is widely used in white and bright-colored products.

It can improve the heat resistance and oxidation resistance of rubber and plastic products, and can prevent the resinization phenomenon in polymer manufacturing and storage.

It can inhibit the phenomenon of gel formation and viscosity increase, and can prevent the thermo-oxidative aging and yellowing of rubber and plastic products.
