Light stabilizers

 Fine white crystals. Melting point 95 ~ 98 ℃. Decomposition temperature> 280 ℃. Dissolved in toluene, acetone, ethanol, ethyl acetate, insoluble in water. The goods and light stabilizer 770 (GW-540 Light  circuit breakers  hindered amine light stabilizer), light stabilizers such polymer materials by capturing produced under ultraviolet light stabilizing active radicals play a role, efficiency of the light stability of the ultraviolet  Electric transformer  is generally several times. This product is not colored, no pollution, good heat processing with antioxidants and UV absorbers, and a good synergy.
