SINOSORB® UV-328 is a high-efficiency ultraviolet absorber, which can effectively absorbs ultraviolet light with a wavelength of 270-340 nanometers.
The light stabilization performance is similar to SINOSORB® UV-326 and SINOSORB® UV-327 but this product has good compatibility with resin, low thermal volatilization, and high washing resistance.
Mainly used for polyolefin (especially polyethylene), polyester, styrenic polymer, polyamide, polymethyl methacrylate, polycarbonate, elastomer and other polymers.
