특수화학소재

UNITECHEM AO-B215 is a physical blend of AO-1010 and AO-168. It is an excellent compound antioxidant with low toxicity, low volatility and high thermal stability. This product has good heat resistance and durability and can effectively prevent the oxidation and yellowing of plastics in the process of processing. The product is suitable for polyolefin, engineering plastics, elastomers, adhesives, rubber and petroleum products. It has good synergistic effect with HALS and UV absorbers.

UV-P is a benzotriazole type UV absorber. It has a high absorption in the wavelength of 270~340nm. It is also efficient for the light stabilization of polyvinyl chloride, unsaturated polyurethane, polystyrene, coatings and lacquers.

Light Stabilizer 770 is a low molecular weight hindered amine light stabilizer with low volatility, migration resistance, and high temperature resistance. It has synergetic effect with antioxidants and UV absorbers. Light Stabilizer 770 is suitable for polyolefin materials, cross-linked polyethylene, olefin copolymers and other polymer materials. It can often be used with other light stabilizers, antioxidants and UV absorbers, to further improve the anti-aging effect of materials. It provides very good light stability for thick sections but can also be used for articles with a high surface area such as films and tapes. It possesses broad compatibility and easy dispersion. Effectiveness of Light Stabilizer 770 is less dependent on the polymer's thickness and for this reason it provides good light stability in articles with higher specific surface such as films and tapes. It exhibits insolubility in water, but good solubility in methanol, ethanol and methylethylbenzene.

UV-5411 is a strong absorber of ultraviolet radiation in the 300-400nm region. It has a low volatility, and especially has good perforin transparent products and high temperature processing engineering plastics.The product is mainly used for polyolefin, pet, PVC, PP, PS, PC, PP fiber, ABS resin, epoxy resin, resin and ethylene vinyl acetate, etc., to protect the polymer from ultraviolet radiation. It improves the anti-aging properties for film, sheet, molding products, fiber products to maintain its appearance and mechanics performance. It can be used together with phenolic antioxidant, phosphite ester antioxidant and hindered amine light stabilizer. Especially suitable for colorless transparent and light products.
