Tiangang® UV-234 is a highly effective UV absorber for polymers processed at high temperatures such as polycarbonate, polyesters, polyacetal, polyamides, polyphenylene sulfide, polyphenylene oxide, aromatic copolymers, thermoplastic polyurethane and polyurethane fibers, where loss of UVA is not tolerated. It protects organic polymers as well as pigments from UV light, improving and preserving the technical and visual performance of such applications. Tiangang® UV-234 features low volatility, exceptional light absorbing characteristics and good compatibility in various substrates. This makes the product especially suitable for applications characterized by high surface area, such as films and fiber.
