UV absorber UV-329

• Benzotriazole UV absorbers
• Uv absorption ability is strong
• It has strong absorbance at 300-400nm
• Excellent thermal stability
• Excellent compatibility with most polymer materials
• It is especially effective in transparent products and engineering plastics

TP-SORB UV-329 is a representative benzotriazole ultraviolet absorber, with excellent ultraviolet absorption, especially in the range of 300~400nm with strong absorbance, and no absorption in the visible region (> 400nm). It can be used in combination with phenolic and phosphite antioxidants and hindered amine light stabilizers to protect the weather resistance of molded products, film materials, sheets and fiber products under outdoor conditions. Widely used in polyolefin, polyester, PVC, PP, PS, PC, polypropylene fiber, ABBS resin and other aspects. Especially suitable for colorless transparent or light-colored products.

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.
