Light stabilizer 744: 4-methyl-benzoyl -2,2,6,6--tetramethyl piperidine
Light stabilizers of 744 properties and uses: this product is a white crystalline powder. 95~98℃ melting point, decomposition temperature of 280 degrees Celsius or more. Soluble in acetone, ethanol, ethyl acetate, toluene and insoluble in water.
Light stabilizer 744 blocked light stabilizer, which itself has almost no ability to absorb ultraviolet light, but can effectively capture polymeric materials produced under the UV reactive free radicals, thereby playing light utility. This product is suitable for polyamide and polypropylene, polyethylene, polystyrene, polyurethane, polyester, of a variety of plastics, especially prominent in the polyolefin. The light resistance for UV absorbers by several times. No coloring, no pollution, good thermal processing, combines with antioxidants and UV absorbers with excellent synergies.
