FEATURE AND APPLICATION

*JADEWIN UV 234 is is a high molecular weight ultraviolet absorber (UVA) of the hydroxy phenyl benzotriazole class, imparting outstanding light stability to a variety of polymers during its use.

* JADEWIN UV 234 is highly effective for polymers usually 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 as well as for polyvinylchloride, styrene homo- and copolymers.

*JADEWIN 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.

* The use levels of JADEWIN UV 234 range between 0.15 and 0.60%, depending on application.

*JADEWIN UV234 can be used in combination with phenolic & phosphite antioxidants, and HALS to optimize performance in outdoor use.
