ANTIOXIDANT JX-168Chemical Name: Tris (2,4-di-tert-butylphenyl)phosphateMolecular formula C42H63O3P Molecular Weight 646 CAS# 31570-04-4 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 stabitor in China.Physical Properties: Appearance: White to offwhite powder Assay: ≥99%Melting Range: 183-187℃ Acid value:(mg KOH/g) ≤0.3%Light Transmittance: 425nm≥98%500nm≥98% Volatiles: ≤0. 3%Hydrolyze time:(h) ≥14 2.4DTBP: (%) ≤0.2Solubility: (At 20℃g/100ml solvent)Water 　　　Insoluble Acetone 1Benzene 　　　　　34 Ethyl Acetate 4Applications: 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. Package: Net 25KGS/two-layer PE bag in carton/drum, or as requiredStorage: Because of the low performance on hydrolyzing resistance, protectionfrom moisture and heat is needed.Period of Validity: About 2 years
