Application Of AO 2105 (THOP TDP)
AO 2105 is an auxiliary antioxidant for organic polymers. It is suitable for many dispersed polymer systems including PVC, ABS, and polyurethane.
Esters, polycarbonates and coatings are all effective liquid phosphite antioxidants. Good in both processing and post-application
Good color and thermal stability can suppress the change of color in the polymerization process such as polyester synthesis and PU foaming, and the general addition amount is 0.1-0.3%.
1. Antioxidant
2. Can be stabilizers for polymer, PU, PVC, polyurethane
3. Additive for resin
