The product is a light stabilizer, which is mainly used in synthetic materials. It can increase the weather resistance and prolong the service life of synthetic materials. It is generally added to synthetic materials in powder form. It is suitable for PVC, epoxy resin, unsaturated polyester and other plastics and coatings. It is an intermediate of benzophenone ultraviolet absorber.

This product is a general chemical product with good storage and transportation stability, non flammable and explosive, non-toxic and harmless.

Properties

Ultraviolet absorber is a kind of light stabilizer, which can absorb the ultraviolet part of sunlight and fluorescent light source without changing itself. Under sunlight and fluorescence, plastics and other polymer materials produce automatic oxidation reaction due to the action of ultraviolet light, which leads to the degradation of polymers and deterioration of appearance and mechanical properties. After adding ultraviolet absorbent, this high-energy ultraviolet can be selectively absorbed to turn it into harmless energy and released or consumed. Due to the different types of polymers, the ultraviolet wavelengths that degrade them are also different. Different ultraviolet absorbers can absorb ultraviolet rays of different wavelengths. When using, ultraviolet absorbers should be selected according to the types of polymers.
