Product Name: Antioxidant 168 Powder CAS 31570-04-4 Model NO.: antioxidant 168 Appearance: Powder Kind: Antioxidant Color: White CAS No.: 31570-04-4 Purity: 95% Min Trademark: LEPUZ Transport Package: in 25kg Carton Specification: C35H62O3 Origin: China Product Description Chemical Name:Tris-(2.4-di-t-butylphenyl) -phosphateMolecular formula: C42H63O3PMolecular Weight: 646CAS: 31570-04-4Introduction: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:AppearanceWhite to offwhite powderMelting Range183-187ºCPurity≥99%Acid value (mg KOH/g)≤0.3%Light Transmittance425nm≥98%500nm≥98%Volatiles≤0. 3%Hydrolyze time (h)≥142,4-t-butyl-phenol (%)≤0.2Applications: The product is akind 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 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.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.ContactPhone: 0086 13584091480
