RUVA-93 by Otsuka Chemical is 2-Propenoic acid 2-methyl-, 2-[3-(2H-benzotriazol-2-yl)-4-hydroxyphenyl]ethyl ester. It is a reactive ultraviolet stabilizer. It is used in plastic lenses, film, sheets, packaging material, containers, fiber, and as alternative plastic to glass. It is a reactive ultraviolet absorber that is able to copolymerize efficiently with a variety of vinyl monomers such as methacrylic, styrenic, and acrylonitrile monomers. Provides permanent placement of the benzotriazole in the polymer. Imparts high weatherability to thin films and fibers. Provides permanence of the stabilizer in the resin and improved compatibility even in very high loadings. RUVA-93 offers excellent environmental acceptability, expanded technology options, and the ability to design new UV polymer screens with unique properties.

PUREstab 1076 is a sterically hindered phenolic antioxidant. It is a highly efficient and non-discolouring stabilizer for organic substrates such as plastics, synthetic fibres, elastomers, adhesives, waxes, oils and fats. It protects these substrates against thermo-oxidative degradation. PUREstab 1076 is odorless, stable to light and has good compatibility with most substrates, low volatility and high resistance to extraction.

PURESTAB B225 is a processing and long-term thermal stabilizer system - is a synergistic blend of PUREFOS 168, an organo-phosphite of low volatility and particularly resistant to hydrolysis which protects during the polymer processing and PURESTAB 1010 a hindered phenolic antioxidant that contributes synergistically to the processing stabilization and provides long-term thermal stability during service life.

PURESTAB 1010 is a high molecular weight hindered phenolic primary antioxidant. It is a highly effective, non-discoloring stabilizer for organic substrate such as plastics, elastomers, synthetics fibres, adhesive and sealant, wax, oil and fats. It protects these substrate against thermo-oxidative degradation.
