GOYENCHEMUV-329 UV Absorber CAS No.3147-75-9

GOYENCHEMUV-329 UV Absorber CAS No.3147-75-9

GOYENCHEMUV-329 meets Reach standard and is effective at 270-380nm and has excellent absorption of UV light. It is also a high-efficiency light stabilizer with low volatility. Provides weather resistance and thermal stability for high temperature products. The advantage is hardly absorbing visible light for colorless transparent products and light-colored products, and non-flammability, safe, and harmlessness, even if processed at high temperature, they will have anti-aging properties, especially for engineering plastics, which are widely used in polyester, polyurethane, PVC, PE, PP, PC, ABS, PMMA and other transparent products and colored products.
