Properties: This product is soluble in resin and has the characteristic of low volatile, high heat resisting, pump resisting, implosion and non-discoloration.
Application: 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 1010) to prepare com-posite 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.
Storage Notes: Sealed stored in cold, dry, good ventilated place, avoid direct sunlight.
