Dragonsorb® 327
Dragonsorb® 327 is a UV absorber that can strongly absorb 270 ~ 400nm ultraviolet light with low volatility and good chemical stability. The combination of the ultraviolet absorber 327 and an antioxidant has an obvious synergistic effect. This product has excellent heat resistance and washing resistance. It has good compatibility with polyolefin and is suitable for polyethylene, polypropylene, PVC, polymethylmethacrylate, polyformaldehyde, polyurethane, unsaturated polyester, ABS, epoxy resin, cellulose resin, etc. The recommended dosage level of this product in plastic is generally 0.3 - 0.5%.
