Description
UV-329 is a highly efficient light stabilizer, with a wide range of UV absorption characteristics, low volatility, suitable for polystyrene, polymethyl methacrylate, polyester, rigid polyvinyl chloride, polycarbonate PC, ABS resin and so on. It play an particularly effective role in modeling transparent products and high temperature engineering plastics processing.
If it is used with antiOxygen additive, it will have high quality synergistic effect which can improve the weathering and thermal oxygen stability.
