Product Description
Bakelite rods are also added with phenolic cloth rods, and the codes are divided into 3723, 3725 according to coarse cloth and fine cloth. The product is made of cotton cloth dipped in phenolic resin and hot pressed by abrasive tools. It has high mechanical properties and processability. The heat resistance grade is grade. It can be used as insulation structure parts in electrical equipment, and can be used in transformer oil. The appearance of the product requires that the surface should be flat, free of bubbles, oil stains and impurities, uneven colors, scratches, slight uneven height, cloth rods with a diameter of more than 25, and cracks on the end face or cross section that do not hinder the use are allowed.

In the application of bearing and gear materials, the use of phenolic cotton plate reduces the sound of machine operation and reduces noise compared with ordinary metal materials. In addition, when running, there is no spark, so it can replace metal materials in explosion-proof environment. Phenolic cotton cloth board products are suitable for manufacturing various gears, rollers, pulleys and guide rails.
