UV-326

UV absorber UV-326 is a light yellow crystalline powder with a melting point of 137-141°C. It is soluble in solvents such as styrene, benzene, toluene and can effectively absorb ultraviolet light of 270-380nm.

It has low volatility and good compatibility with resin. It is mainly used in polyolefin, polyvinyl chloride, unsaturated polyester, polyamide, polyurethane, epoxy resin, ABS resin and cellulose resin. It is suitable for natural rubber and synthetic rubber. It has good stability, low toxicity, and no irritation to the human body. It is widely used in coatings, synthetic rubber, synthetic fibers, photosensitive materials, etc. It can effectively improve the light resistance of these materials and reduce yellowing and aging caused by ultraviolet excitation in the sun. and other phenomena.

It has a wide range of non-food direct contact permissions in polyolefins. It has low volatility at high temperatures and high resistance to thermal degradation. Therefore, it can reduce decomposition losses during polyolefin polymerization and film compression molding. UV protection is used in polyester resin. This product will not form metallic colored salts during the heating process of the resin.
