Texas may Lyle Plastic Co., Ltd. is a company specializing in plastic masterbatch development, production and sales of high-tech enterprises masterbatch, conveniently located in the valley of China - Dezhou. . Products, "Wong Chun Bird" brand masterbatch, functional masterbatch, are using high-quality processing of raw materials, and has passed ISO9001-2000 international quality management system certification. Its products are non-toxic and environmentally friendly, high heat resistance ,, stability, heavy metal content is low. Light Stabilizers for the plastics and other polymers absorb UV energy can cause auto-oxidation reaction and lead to degradation. This process is known as photo-aging or photo-oxidation, can inhibit or delay substance known light stabilizers of this process. The 1940s, the first use of phenyl salicylate as a light stabilizer in cellulose acetate. In the early 1950s and early 1960s were the emergence of benzophenone and benzotriazole Baise masterbatch, the mid-1970s and the emergence of a hindered amine light stabilizer. Light stabilizers are used primarily for polyolefins Shandong masterbatch, especially polypropylene. PVC, polycarbonate, polyester also use a small amount of light stabilizer may Lyle masterbatch, which with about 0.1% to 0.5%. According to their mechanism of action, an ultraviolet absorber light stabilizers, quenchers, light shielding agent points. Ultraviolet absorber strongly absorbs ultraviolet light 290 ~ 400nm wavelength, 2-hydroxy-4-octyloxy-benzophenone (UV-531) and 2- (3 ', 5'-di-t-butyl-2'-hydroxy- phenyl) -5-chlorobenzotriazole (UV-327) is the best of the two varieties. Most nickel-quencher organic complex. Excited molecules can quickly and effectively absorb the energy of quenching (return to equilibrium) to avoid triggering the photochemical reaction. Light shielding agent may weaken the role of UV transmission, usually black. New hindered amine light stabilizers are mainly four or five methylpiperidine methyl alcohol derivatives which have capture free radicals, quenching singlet oxygen and peroxide decomposition integrated functions, therefore it is effective light stabilizer.
