* Application:
Tinuvin 234 is highly effective for polymers usually processed at high temperatures such as polycarbonate, polyesters, polycetal, polyamides, polyphenylene 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. Applicatins include molded articles, films, sheets and fibers.
* Features:
Tinuvin 234 features low volatility, exceptinal light absorbing chracteristics and good compatibility in various substrates. This makes the product especially suitable for applications characterized by high surface area, such as films and fibe. It protects organic visual performance of such applications. Tinuvin 234 has world wide Food Contant Approvals in most polymers and is especially suitable in packaging applications for food, consumer care products and pharmaceuticals, preserving the package contents from the detrimental effects of light. |
