Blue Sanding Film Disc
The blue sanding film disc uses a unique sand-planting process to coat zirconium corundum abrasives on a polyester film, ensuring the abrasive is closely bonded to the substrate. The sanding disc maintains good grinding performance even after long-term use, extending its service life.
Product Introduction
Technology First
We offer a variety of transmission components
Fast Surface Leveling Performance
- High-density zirconia abrasive coating with a sharp cutting structure.
- Quickly removes sanding marks, surface defects, and uneven coating layers.
- Improves sanding efficiency during automotive repair and industrial surface preparation.
- Suitable for high-speed material removal on primer, filler, and metal surfaces.
Flexible Film Backing for Contour Sanding
- Thin yet durable polyester film construction.
- Adapts smoothly to curved edges and irregular workpieces without cracking.
- Provides more controlled sanding on body lines, corners, and shaped surfaces.
- Widely used for contour sanding in automotive refinishing and furniture production.
Reduced Heat Build-Up During Sanding
- Engineered sanding surface with optimized friction control.
- Helps minimize excessive heat generation during continuous machine sanding.
- Protects painted surfaces from overheating and reduces premature abrasive wear.
- Effective for long-cycle orbital sanding and paint preparation processes.
Consistent Finishing from Start to Finish
- Uniform resin bonding and abrasive distribution.
- Maintains stable sanding performance throughout the disc lifespan.
- Helps operators achieve repeatable surface quality with fewer sanding defects.
- Ideal for applications requiring controlled finishing before coating or polishing stages.
High-Quality Substrate: The blue film sanding disc is made of high-quality zirconium corundum abrasives and polyester film, providing high hardness, toughness, and wear resistance. It can quickly remove defects such as burrs, rust, and welds from the workpiece surface, ensuring fast
and efficient metal cutting. The uniform distribution of abrasive particles guarantees consistent grinding results, leaving the workpiece surface flat and smooth.
Convenient Velcro Connection: The back of the Velcro film sanding disc uses a hook-and-loop system to securely attach to the polishing pad, effectively preventing slipping or warping. This ensures precise control during grinding, even under high-speed rotation or heavy loads. The Velcro backing also facilitates easy replacement and positioning of the sandpaper, reducing labor intensity and improving overall work efficiency.
Hole Design for Rapid Heat Dissipation: The blue sanding film disc features holes that ensure effective dust removal during grinding, maintaining a clean working area and reducing the risk of clogging. The perforations also allow rapid heat dissipation, minimizing the risk of deformation or damage to the workpiece and protecting the sandpaper from thermal degradation, thereby maintaining its operational integrity.
Versatile Applications: Zirconium oxide film sanding discs are suitable for removing welds, burrs, and sharp edges and for preparing metal surfaces for painting or coating. They are also ideal for sanding wooden surfaces in furniture making, removing old paint, varnish, or stains, and eliminating paint and rust from car bodies.
