Electronic materials cover a very wide range. Polyurethane materials can also be used in grinding and polishing of electronic products. At present, they have been widely used in the production of friction sheets and polishing sheets for grinding or polishing LCD screens of electronic products. The main requirements of this type of product are: good wear resistance, good film-forming property, high hardness, good impact resistance, etc. Our current products are mainly divided into wet-process polyurethane resin for impregnated friction discs and wet-process polyurethane resin for scratch-coated and polished discs.
