Applications:
UV 327 shows good thermal stability, low volatility, good compatibility with polyolefins. It hardly absorbs visible light, especially suitable for colourless, transparent and light-coloured products. Tinuvin 327 is suitable for polyolefin, polyvinyl chloride, polymethyl methacrylate, polyoxymethylene, polyurethane, and ABS resin, especially suitable for polypropylene fiber.
Recommended dosage: polyolefin 0.2-0.6%, PVC 0.2-0.5%, ABS resin 0.3-0.5%.
