P-24Molecular Weight: 604Chemical StructureSpecification : Item RequirementsAppearance White crystalline powder or grainsMelting point，℃ ≥160Volatiles，wt% 0.5% maxAsh 0.1% maxAssay 95% minApplications: 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 AO-1010) 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. Packing: 25 Kg in each cardboard box with plastic lining.
