Applications
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. Applications include molded articles, films, sheets and fibers.
Features/ Benefits
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. It protects organic polymers as well as pigments from UV light, improving and preserving the technical and visual performance of such applications.
UV 234 has world wide Food Contact 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.
Guidelines for use
The use levels of UV 234 range between 0.15 and 0.60%, depending on Substrate and performance requirements of the final application. Extensive Performance data of UV 234 alone or in combination with other additives are available in many of the substrates listed above.
Handling & Safety
In accordance with good industrial practice, handle with care and avoid Unnecessary personal contact. Avoid continuous or repetitive breathing of Dust. Use only with adequate ventilation. Prevent contamination of the Environment. Avoid dust formation and ignition sources. For more detailed Information please refer to the material safety data sheet.
