Function
UV-234 is a benzotriazole type ultraviolet absorber that can absorb 300-400 nanometers of ultraviolet light and a small amount of visible light. It has the characteristics of good compatibility, low volatility, good thermal stability, high absorption efficiency, and is suitable for high temperature and large surface area films and fibers, especially for polyester, polycarbonate, PVC, polystyrene, polyformaldehyde, polyamide, polyimide, polyphenylene ether, polyphenylene sulfide. When combined with light stabilizers and antioxidants, the synergistic effect is significant. The general dosage is 0.1-0.5%.
Product Usage
It is applicable to packaging of polycarbonate, polyester, polyacetal, polyamide, polyphenylene sulfide, polyphenylene oxide, aromatic copolymer, thermoplastic carbamate and polynenenebb carbamate fiber food and medicine, and is allowed to be used together with other light stabilizers or antioxidants.
