Applications
Phenolic benzotriazole is highly effective for polymers processed at high temperatures such as polycarbonates, polyalkylene terephthalates, polyacetals, polyamides, polyphenylene sulfide, polyphenylene oxide, aromatic copolymers, thermoplastic polyurethane and polyurethane fibers, as well as for polyvinylchloride, styrene homo- and copolymers.
Applications include molded articles, films, sheets and fibers.
Use levels of Phenolic benzotriazole range between 0.15 and 0.60 %, depending on substrate and performance requirements of the final application.
Phenolic benzotriazole can be used alone or in combination with other functional additives such as antioxidants (hindered phenols, phosphites) and HALS light stabilizers, where often a synergistic performance is observed.
Extensive performance data of Phenolic benzotriazole alone or in combination with other additives are available in many of the substrates listed above.
Low volatile benzotriazole UV light absorber and stabilizer.
Imparts outstanding light stability for polymers processed at high temperatures such as polycarbonate, polyesters, polyacetal, polyamides, polyphenylene sulfide, polyphenylene oxide, aromatic copolymers, thermoplastic polyurethane and polyurethane fibers also highly effective for polyvinylchloride, styrene homo- and copolymers.
