| ultraviolet absorber | light stabilizer 770, sebacic acid di (2,2,6,6-tetramethyl -4-piperidinyl) ester. Among the world’s first hindered amine light stabilizer products born in the 1970 s, 770 is the only hindered amine product still used in the contemporary plastic industry. The annual consumption of domestic 770 accounts for about 20% of the total consumption of hindered amine light stabilizer. The quality of domestic 770 products is close to the level of foreign 770 products, and domestic 770 exports a certain amount every year. Light stabilizer 770 is mainly used as a high-efficiency hindered amine light stabilizer, suitable for polypropylene, polyethylene, ABS resin and polyurethane. The product characteristics are as follows: 1. It can effectively absorb ultraviolet rays with a wavelength of 290-400nm, or can quench the energy of excited state molecules, or has the ability to capture free radicals. 2. Its own light stability and thermal stability are good. 3. Good compatibility and no exudation during use. 4, resistant to hydrolysis, water and other solvent extraction. 5. Low volatility and low pollution. 6, non-toxic or low toxicity, cheap and easy to obtain. |

| properties | light stabilizer 770 appearance is white crystalline powder. Melting point 81 ℃ ~ 86 ℃, soluble in ethanol, ethyl acetate, benzene and other organic solvents, insoluble in water. It is a representative variety of low molecular weight HALS. Its light stabilization efficiency is high, suitable for polyethylene, polypropylene, polystyrene, ABS and other products, especially in polyolefin products, the light stabilization effect is 3 to 4 times that of ultraviolet absorber and nickel quencher, due to the relative molecular mass Small, high volatility, poor migration resistance and extraction resistance, it is suitable for use in thick products. |
| application | light stabilizer 770 is suitable for polypropylene, high density polyethylene, polyurethane, polystyrene, ABS resin, etc. 770 light stabilization effect is better than that of commonly used light stabilizer at present. Combined with antioxidants, it can improve heat resistance, and it also has a synergistic effect with ultraviolet light absorbers, which can further improve the photostability effect. mixed light stabilizer 944, light stabilizer 770. This is an excellent UV stabilizer, especially PP thick section, providing excellent surface protection. It also shows high stability rate PP tapes. Light stabilizer 791 application PP, PP / EPDM andPP/polyethylene/ethylene propylene diene monomer bren (TPO). Light stabilizer 791 is an excellent thick part of ultraviolet stabilizer, such. Automobile bumpers, fascia, etc. are mainly used as high-efficiency hindered amine light stabilizers, suitable for polypropylene, polyethylene, ABS resin and polyurethane, etc. used for polypropylene, high-density polyethylene unsaturated resin, Polyurethane, polystyrene and ABS resin, its light stabilization effect is better than the currently commonly used light stabilizers |
