Applications:

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. Used as tinuvin 328 equivalent.

UV 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%.
