UV 320 is an efficient light stabilizer with strong UV absorption and low volatility. It can effectively protect polyester and organic pigments from ultraviolet radiation, thereby protecting the appearance of molded objects, films, fibers, etc. UV 320 is suitable for polyvinyl chloride, unsaturated polyester and other polymers. Used as tinuvin 320 equivalent.
Recommended dosage: polyester 0.3-0.5%, PVC 0.25-0.5%, unsaturated polyester 0.2-0.5%.
