Description:
Hangzhou Sunny Chemical Corp.Ltd. Http://www.sunnychemical.com Polymer additives are added with small amounts to protect polymers’ performance by preventing loss of mechanical strength, cracking, crazing, yellowing, and loss of gloss due to day-to-day exposure to air and light. Our polymer additives, including UV absorbers, Antioxidants, Photoinitiators, Optical Brightener Agents (O.B.A.) and Colorants. The recommended polymer additives hold the following advantages: 1) Excellent chemical stability 2) Excellent heat stability 3) Good compatibility with polymer 4) Low volatility 5) Low toxicity and small pollution UV absorber ( Benzophenone): UV-9 : 2-Hydroxy-4-methoxy benzophenone CAS No. 121-57-7 Against Cyasorb UV 9 Formula C14H12O3 Molecular weight 228.25 UV-531 : 2-Hydroxy-4-octoxy benzophenone CAS No. 1843-05-6 Against Cyasorb 531 Formula C21H26O3 Molecular weight 326.43 UV absorber ( Benzotriazole) UV-P : 2-(2'-Hydroxy-5'-methylphenyl)-Benzotriazole CAS NO. 2440-22-4 Against Tinuvin P UV-326 : 2-(2'-Hydroxy -3' -tert-butyl-5'-methylphenyl)-5-chloro benzotriazole CAS NO. 3896-11-5 Against Tinuvin 326 (Ciba) UV-327 : 2-(2'-Hydroxy -3' ,5'-ditert-butylphenyl)-5-chloro benzotriazole CAS NO. 3864-99-1 Against Tinuvin 327 UV-328 : 2-(2'-Hydroxy -3' ,5'-ditert-butylphenyl)- benzotriazole CAS NO. 25973-55-1 Against Tinuvin 328 UV-329 : 2-(2'-hydroxy-5'-tert-octyllphenyl)benzotriazole CAS NO. 3147-75-9 Against Tinuvin 5411 (Ciba) UV absorber (HALS) Horsorb 292 : Bis(1,2,2,6,6-pentamethyl-4-piperidyl)sebacate and 1-(Methyl)-8-(1,2,2,6,6-pentamethyl-4-piperidinyl)sebacate Against Tinuvin 292 (Ciba-Geigy); Eversorb 93 (Everlight) CAS NO.: 41556-26-7 and 82919-37-7 Horsorb 622 : Poly[1-(2'-Hydroxyethyl)-2,2,6,6-tetramethyl-4-hydroxy piperidylsuccinate Against Tinuvin 622 (Ciba-Geigy); CAS NO.: 65447-77-0
