Description:

UV-327 is a white or canary powder, melting point 154～158 ℃, soluble in organic impregnant, such as benzene, toluene, styrene; well soluble in multiplicate resins; insoluble in water. It is an efficient ultraviolet radiation(270～380nm) absorbent with low volatility, insensitive with metal ions; used for polyolefin(especially used in food production), PVC, PUR ,polyurethane , ABS resins and AS resins and so on. Thanks to its low toxicity, it’s well recognized as an excellent plastic additive.

Usage:

UV-327 can improve its capability when used together with antioxidant, such as DLTDP. Commonly , the product’s dosage is 0.1%～0.3%.

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