AI Overview

TNPP, or

Tris(nonylphenyl)phosphite, is a high-stability antioxidant primarily used to prevent discoloration and degradation in plastics and rubbers during processing. It works by improving color stability, protecting against thermal oxidation, and preventing the formation of resins, gels, and viscosity increases. Due to its effectiveness in preserving color, it is widely used in white and light-colored products and is often combined with phenolic antioxidants for a synergistic effect.

What it is

Protects against degradation: TNPP guards against degradation caused by heat during the manufacturing and processing of polymers like PVC, PE, PP, and ABS.
Maintains color: It is particularly effective in preventing discoloration in white and light-colored products, as it does not affect the final product's color.
Synergistic effect: It works well in combination with other antioxidants, such as hindered phenols, to provide a more comprehensive protection.
Improves stability: It helps prevent resin-forming, gel formation, and increases in viscosity that can occur during processing and storage.
