Antioxidant HP136,2(3H)-Benzofuranone,5,7-bis(1,1-dimethylethyl)-3-(3,4-dimethylphenyl) Usage And Synthesis

Description

Antioxidant 136 is an effective carbon radical antioxidant. It has good effects when used with phenolic and phosphite antioxidants. As a carbon center free radical antioxidant, this product can effectively inhibit the oxidation reaction caused in the initial stage. Used together with a low-volatility organic phosphite auxiliary antioxidant, it protects the polymer during reprocessing by decomposing hydroperoxide.

Uses

Antioxidant 136 is mainly used in polypropylene (PP), suitable for the processing of large-scale extrusion equipment under high temperature conditions, and can inhibit the yellowing of polymers.
