-(1,4-PHENYLENE)BIS-4H-3,1-BENZOXAZIN-4-ONE - Reference Information

light stabilizer 3638 light stabilizer is an additive for polymer products (such as plastics, rubber, coatings, synthetic fibers). It can shield or absorb ultraviolet energy, quench singlet oxygen and decompose hydroperoxide into inactive substances, under the radiation of light, the polymer can eliminate or slow down the possibility of photochemical reaction, prevent or delay the process of photoaging, so as to achieve the purpose of prolonging the service life of polymer products. Light stabilizer 3638 is a new generation of environmentally friendly and efficient ultraviolet absorber. It has efficient absorption of UVB and UVC. High molecular weight, low volatility, colorless stain. It is especially suitable for optical industries with high requirements on light transmittance and color, such as PET,PC optical material lenses, light diffusion plates of backlight liquid crystal display devices, etc. Light stabilizer 3638 has high heat stabilizer, TGA(10%) is greater than 371 degrees Celsius. It is especially suitable for thermoplastic polyester, nylon and defense industries with high processing temperature and strict requirements on ultraviolet absorption effect. Light stabilizer 3638 is FDA approved food contact material additive. Especially suitable for high-end PET packaging materials and PET materials with high compatibility, do not participate in the PET polyester polymerization process reaction high temperature resistance, high pressure resistance, acid and alkali resistance, low addition and in the process of processing and storage, no decomposition, no precipitation, no migration.
