Bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate CAS 52829-07-9
Light stabilizer 770 is a white or slightly yellow crystalline powder, which is a typical low molecular weight product among many hindered amine light stabilizers. It is soluble in organic solvents such as ethanol, ethyl acetate, benzene, and insoluble in water. It is a representative variety of low molecular weight HALS. It has high photostability and is suitable for products such as polyethylene, polypropylene, polystyrene, ABS, etc. Its photostability effect is 3-4 times that of ultraviolet absorbers and nickel quenchers, especially in polyolefin products. Due to its small relative molecular weight, high volatility, poor resistance to movement and extraction, it is suitable for use in thick products.

Bis (2,2,6,6-tetramethyl-4-piperidyl) sebacate is suitable for polypropylene, high-density polyethylene, polyurethane, polystyrene, ABS resin, etc. Its 770 light stabilization effect is superior to commonly used light stabilizers. When used in combination with antioxidants, it can improve heat resistance, and when used in combination with UV absorbers, it also has a synergistic effect, further enhancing the photostability effect. Bis (2,2,6,6-tetramethyl-4-piperidyl) sebacate is used for polypropylene, high-density polyethylene unsaturated resin, polyurethane, polystyrene, and ABS resin, and its photostability effect is superior to commonly used light stabilizers
Usually packed in 25kg/drum,and also can be do customized package.
