特殊化學品

Luna-vin VYHH-W is a versatile copolymer, perfect for a wide range of applications. It is made from a blend of vinyl chloride and vinyl acetate, giving it excellent adhesive properties that make it ideal for use in adhesives, packaging, and wood finishes. It is also a great choice for use in general metals, inks, and marine and maintenance applications.

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.

PUREFOS 168 is a hydrolytically stable phosphite processing stabilizer. It acts as a secondary antioxidant during plastic processing and protects the polymer matrix by reacting with the hydroperoxides formed at this stage by auto-oxidation. The combination of PUREFOS 168 with primary antioxidants provides a synergistic stabilization activity, preventing the overall thermo-oxidative degradation of the material.
