Chemical name: Bis(2.4-di-t-butylphenyl) Pentaerythritol Diphosphite
Molecular Formula: C33H50O6P2
CAS NO.: 38613-77-3
Characteristics and Uses:
The product is a kind of high-effective solid phosphite ester antioxidant, which is superior to other phosphite ester in the effective protection of polymers' color. It is often blended with phenolic principal antioxidant (such as AT-10) to prepare composite antioxidant which improves the thermo-stability of polymer processing, thus making it widely applied in PE, PP, PS, PA, PC, ABS and many other polymer materials
Storing and Packing:
Because of the low performance on hydrolyzing resistance, protection from moisture and heat is needed. The package should be cardboard boxes with plastic liners, net weight: 25Kg / box.
