Description
Tinuvin 328, also known as light stabilizer 328, is a benzotriazole ultraviolet absorber and one of the excellent light stabilizers. It has the characteristics of stable performance, low toxicity, strong ultraviolet absorption ability, good compatibility with resin, low thermal volatility and high washing resistance. Tinuvin 328 has antioxidant properties and can be used in combination with general antioxidants. Tinuvin 328 can effectively absorb ultraviolet rays in the 270-380nm band, and the maximum absorption wavelength is 345nm. Tinuvin 328 can be used not only for polypropylene, polyethylene, polyolefins (especially polyvinyl chloride), polystyrene, polyester, polyurethane, styrene, polyamide, polycarbonate, etc., but also for plexiglass , ABS resin, coatings, petroleum products and rubber, etc. In addition, Tinuvin 328 is also allowed to be used in plastic packaging materials in contact with food and children's plastics.
