Abrasive Key Component of Abrasive Tools

When choosing an abrasive for polishing plastic, extra care has to be taken in selection to prevent scratching or further damaging the plastic surface. Polishing abrasives are often of a soft nature like cerium oxide or fine grained silicon carbide. These abrasives soften plastic residues without overexerting abrasion while polishing soft plastics that have low molecular weight and fine scratches. This type of abrasive is important in the production of high-gloss plastic parts like acrylic displays or polycarbonate lenses. The granular structure of the abrasive is carefully controlled, finer grits applied in the last stages of polishing. That way the plastic surface will be smooth and shiny to achieve superior polish.
