HYDROLYSIS POSSIBILITY: this product immerses in water or is exposed to wet air for a long time. Different degrees of hydrolysis cause the product to clot until fully liquefied.This product can effectively prevent thermal degradation of polypropylene and polyethylene in basic injection molding, and give extra long-term protection to the polymer.This 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 comp0site 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.
Introduction: This product is soluble in resin and has the characteristic of low volatile, high heat resisting, pump resisting, implosion and non-discoloration. At present, it is the best processing stabilizer in china.Physical Properties: white powder Assay: ≥99%
Melting range: 183-186℃ Acid value: ≤0.3% Light Transmittance: 425nm≥96% 500nm≥98% Volatiles: ≤0.5% hydrolyze time:≥14, free 2,4-di-tert-butyl-phenol≤0.2.
Packing: Net 25kg/drum,cardboard boxes with plastic liners;or as required.
Storage: Because of the low performance on hydrolyzing resistance, protection from moisture and heat is needed.
