Polyester Abrasive Film Disc for Automotive Primer & Dry Sanding
Polyester abrasive film discs consist of a polyester film backing combined with zirconium corundum abrasives. This high-quality abrasive, made from aluminum oxide and zirconium oxide fused at high temperatures, offers longer service life and higher efficiency. Zirconium corundum provides superior hardness and cutting ability, making it ideal for precision grinding and polishing of metal and non-metal materials in industries such as automotive painting and repair, woodworking, and 3C manufacturing.

High Grinding Efficiency: Polyester abrasive film discs deliver excellent grinding performance, quickly removing material from the workpiece surface and improving overall efficiency. The fine, uniformly distributed abrasive particles produce a smooth and refined surface finish, meeting the demands
of high-precision processing.
Wear-Resistant Zirconium Oxide: The zirconium abrasives in polyester film discs fracture into smaller, sharper edges as they wear, giving them a self-renewing property that extends the product's service life. The even distribution of abrasives helps maintain a smooth, consistent grinding surface, while the sharp edges ensure fast cutting and improved productivity.
Convenient Connection Design: The Velcro backing on the polyester green film disc allows it to adhere firmly to the workpiece surface, enhancing grinding and polishing quality. The disc can be quickly replaced without interrupting workflow, ensuring a secure fit and minimizing slippage during sanding.
Multiple Application Areas: Polyester green film sanding products are suitable for grinding, polishing, and sanding a wide range of materials, including metal, non-metal, and composite materials.
