Description:

UV-326 is a canary powder, melting point about 138℃, soluble in benzene, styrene, toluene; well soluble in multiplicate resins; insoluble in water. It is an efficient ultraviolet radiation (270～380nm)absorbent and light stabilizer with low volatility; insensitive with metal ions; used for polyolefin(especially used in food production), PA, POM, PVC, PUR,polyurethane , ABS resins and AS resins and so on; widely used in color film , chromophotograph, dope, oil paint and macromolecule . Thanks to its low toxicity, it’s well recognized as an excellent plastic additive.

Usage:

UV-326 can improve its heat-resistance and heat-stability when used together with antioxidant. Commonly ,the product’s dosage is 0.1%～0.5%.

Storage:To be kept in a cool and dry place.

Packing: meet buyer’s requirement
