Anti-ultraviolet aging Masterbatch is composed of reactive light stabilizer and anti-oxidant, which can effectively eliminate and weaken the damage of UV light to plastics, but does not affect other properties of plastics. Light stabilizer itself has excellent light stability, not destroyed by light energy, and polymer has good compatibility, non-volatile, non-migration. Low absorption of visible light, no coloring, no discoloration, processing stability, does not affect the processing performance of the polymer.
