Grinding wheel
Introduction of industry
Abrasive materials are mainly composed of binder, grain, class fiber, cloth, paper, synthetic fiber, and etc. Phenolic resin plays an important role in process procedure of wetting, coating, impregnate, binding, adhesive, and disperse. Phenolic resin is widely used in grinding wheel, abrasive paper, sand cloth, and grinding tools for improve the performance of waterproof, heat resistance, wear resistance, and adhesion.
Applicaton: grinding wheel, sand cloth, abrasive paper, abrasive cloth, coated abrasive.
