Applications of UV Absorber UV 328

UV 328 is a high-performance UV absorber that can effectively absorb 270-340 nm UV light. Its performance is similar to that of UV-326 and UV-327 while better compatibility with the resin, low thermal evaporation and high washing resistance. Tinuvin 328 is suitable for polyolefin (especially polyethylene), polyester, styrene polymer, polyamide, polymethyl methacrylate, polycarbonate, elastomer and other polymers.

Recommended dosage: PS 0.2-0.5%, PE 0.2-0.4%, PC 0.15-0.3%, PVC 0.2-0.5%, Polyester 0.3-0.5%.

Package of UV Absorber UV 328

UV Absorber UV 328 is packed 20kg/25kg per fiber drum lined with plastic bag, stored in cool and dry place without direct sunlight.
