Usage

Description

1,1,3-Tris(2-methyl-4-hydroxy-5-tert-butylphenyl)butane is a white crystalline powder that serves as an exceptional phenolic antioxidant.

Uses

Used in Plastics and Rubber Industry:
1,1,3-Tris(2-methyl-4-hydroxy-5-tert-butylphenyl)butane is used as a stabilizer for various resins such as polypropylene, polyethylene, polyvinyl chloride, ABS, and polyoxymethylene. It is particularly beneficial for light-colored rubber products due to its ability to prevent degradation and discoloration caused by oxidation.
Additionally, it is used as a synergistic antioxidant alongside DLTP, enhancing the overall stability and performance of the materials in which it is incorporated. This makes it a valuable component in the production of plastics and rubber goods that require resistance to heat, light, and oxygen-induced degradation.
