Blue Film Velcro Disc
The blue film velcro disc is made of flexible blue film backing and premium zirconium corundum abrasive. The hook-and-loop sanding discs have better durability and service life, ensuring stable performance even after long-term use. Ideal for automotive refinishing, wheel polishing, high-precision manufacturing (3C products and ceramic parts), metal mirror finishing (stainless steel, aluminum alloy), etc.
Product Introduction
Stable grinding effect: The blue film velcro discs are made of premium zirconium oxide abrasives, which have a better grinding ability due to their evenly distributed abrasive particles and can quickly and effectively eliminate defects and irregularities on the workpiece surface. The uniform distribution of abrasive particles guarantees the stability of the grinding process and helps to control the workpiece surface precisely, thereby reducing the risk of over-grinding or under-grinding.
Convenient hook-and-loop fastening system: The hook-and-loop fastening system of the zirconium film sanding disc can be easily installed and removed from compatible sanders equipped with velcro backing, thereby improving operating efficiency and minimizing downtime. This user-friendly feature simplifies abrasive replacement and maximizes productivity for various grinding applications.
Versatile and adaptable: The blue film sanding discs are suitable for a variety of materials, including wood, metal, plastic, and composite materials. Its performance is comparable to Deerfos film SA331.
