UV absorber UV-327
UV absorber UV-327
Features and Advantages
  • High temperature resistance, good thermal stability, can be used for plastic products requiring high temperature processing
  • Not sensitive to metal ions
  • Almost does not absorb visible light, especially suitable for colorless transparent and light-colored products
  • It has strong absorption effect on ultraviolet light
  • Constant yellow under alkaline conditions, oil resistant
  • Low volatility, less loss during processing
Product Application

TP-SORB UV-327 is an excellent benzotriazole ultraviolet absorber, and the absorption wavelength range is larger than that of ultraviolet absorber UV-P. Can strongly absorb 300-400 nm of ultraviolet light, the highest absorption peak is 353 nm, and good chemical stability, small volatility, and polyolefin phase Chemicalbook solubility is good, especially suitable for polyethylene (PE), polyvinyl chloride (PVC), polystyrene and polypropylene (PP), can also be used for polymethyl methacrylate, poly Formaldehyde, unsaturated polyester, polymethylenate methyl ester, polyurethane, ABS resin, polypropylene fiber, coatings, colorants, adhesives, candle wax and other polymers and many other fields. Low toxicity, non-inflammable, non-corrosive, good storage stability, and the use of thioester antioxidant DLTDP has significant synergistic effect.

Safety and protection

The package is 20kg or 500kg/ bag, which can be customized. No special safety equipment is required, according to the general chemicals cool, dry, ventilated storage, away from fire, heat sources, strong oxidants, strong reducing agents. It is recommended to take proper protective measures, try to avoid long-term contact with the product, and rinse with plenty of running water after contact with eyes or skin. Keep for 12 months under suitable storage conditions. Additional safety and operational information can be found in theTP-SORB UV-327 SDS.
