May 14, 2024

Main components: properties and characteristics of stilbene bisbenzoxazole type compounds : 1. Small dosage, high whitening strength, very small amount can produce very good whitening effect. 2. Wide application performance, widely used in whitening of chemical fibers such as polyester and various plastics. 3. Has good compatibility with plastics, high temperature resistance and excellent light fastness and weather resistance. Scope of application: Fluorescent brightener KSN and OB-1 have similar chemical structure, but the whitening effect on polyester fiber and plastic products is better than OB-1, and the compatibility with plastic is better than OB-1. Very little use can produce very good whitening effect, which is far less than OB-1. KSN not only has excellent high temperature resistance, but also has excellent solar and weather resistance. Fluorescent brightener KSN is also suitable for whitening of polymer fibers such as polyamide and polyacrylonitrile. It can also be used in film, injection molding and extrusion materials. It is very suitable for adding KSN in any processing stage of synthetic polymer. Good whitening effect. Application method: The optical brightener KSN is equivalent to 0.01-0.05% of the weight of the plastic or polyester pellets, and can be thoroughly mixed with the materials before the various plastic molding processes or before the polyester fibers are drawn. The specific dosage is adjusted according to the formula. Technical indicators: Appearance: bright yellow powder, purity ≥ 98%, melting point: ≥ 295 ° C, volatility: ≤ 0.5%, fineness > 100 mesh. Packing and storage: 25kg cardboard drum, stored in a cool, dry place away from light.
