(13003-12-8) 4,4'-butylidene-bis(3-methyl-6-t-butylphenyl ditridecyl)phosphite
Product Description
A polymeric phosphite antioxidant with high molecular weight and high phosphorus content, which has good performance in improving the hydrolysis resistance, heat resistance, stability, and color improvement of thermoplastics, rubber, and PVC products. As a secondary antioxidant, it has a strong ability to decompose hydroperoxides. It has a good synergistic effect with the main antioxidant, which can improve the antioxidant effect and reduce product costs.
Suggested addition amount: 0.1–2.0%.
