Typical Properties: It takes on an appearance of white crystalline powder or grains. The melt point ranges from 160℃ to 180℃. Flash point: 168℃ kindling point: 421℃ stacking density:0.43g/mL lower limit concentration of dust explosion: 0.12Kg/m3 explosion index: 0.37 soluble in organic solvents like toluene, dichloromethane, and slightly soluble in alcohols but insoluble in water.
Applications: 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 JYANOX-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.
Storage & Transportation: Because of the low performance on hydrolyzing resistance,protection from moisture and heat is needed.
Packing: cardboard boxes with aluminum foil bag inside, net weight: 20Kg / box.
