UV Absorber UV-329 J6104 excellent compatibility polypropylene fiber ABS resin
UV Absorber UV-329 is a highly efficient benzotriazole-based light stabilizer with outstanding performance. This product effectively absorbs ultraviolet light in the 270-360 nanometer (nm) range. Through the formation and conversion of intramolecular hydrogen bonds, it dissipates high-energy UV radiation as thermal energy, thereby protecting polymer chains from damage caused by ultraviolet radiation.

Product Features:
Characterized by light color, non-toxicity, excellent compatibility, low migration, and ease of processing. It provides maximum protection for polymers, helps reduce color fading, delays yellowing, and inhibits physical property degradation.
IV. Product Applications:
UV absorber UV-329 is a high-performance anti-aging agent that absorbs ultraviolet light between 270-360 nm. It is widely used in PE, PVC, PP, PS, PC, polypropylene fiber, ABS resin, epoxy resin, resin fiber, and ethylene vinyl acetate applications. This product shields polymers from UV radiation, protecting molded products, film materials, sheets, and fiber products from weathering under outdoor conditions while maintaining their appearance and mechanical properties. In outdoor applications, it can be used in combination with phenolic antioxidants, phosphite antioxidants, and hindered amine light stabilizers. It is particularly suitable for colorless, transparent, and light-colored products. It can also be used in packaging materials such as plastic containers and food packaging boxes, providing excellent light stabilization effects.
V. Product Packaging:
25 kg/drum. Store in a cool, dry, well-ventilated warehouse away from fire sources, heat sources, and direct sunlight. Avoid high temperatures and humid environments.
