Synsorb-234 is highly effective for polymers usually processed at high temperatures such as polycarbonate, polyesters, polyacetal, polyamides, polyhenylene sulfide, polyphenylene oxide, aromatic copolymers, thermoplastic polyurethane and polyurethane fibers, where loss of UVA is not tolerated as well as for polyvinylchloride, styrene homo- and copolymers. Applications include molded articles, film, sheets and fibers. The use levels of Synsorb-234 range between 0.15 and 0.60%, depending on substrate and performance requirements of the final application.
