UV-328function
Ultraviolet Absorbent Tinuvin 328 is a highly efficient light stabilizer for a variety of plastic and organic substrates. Recommended for homopolymer/copolystyrene, polyacrylate, unsaturated polyester, polyvinyl chloride, polyolefin, polyurethane, polycarb, polyacetal, polyvinyl butyral, elastomer and binder.
Tinuvin 328 is characterized by strong UV absorption, light initial color, good compatibility with most substrates, and low volatility.
It protects polymers and organic pigments while maintaining the consistency of the original appearance and physical properties of the surface of molded articles, films, fibers and sheets for outdoor use.
