Blue Film Polishing Disc
The blue film polishing disc is made of polyester film, which is tear-resistant and heat-resistant. High-quality zirconium aluminum abrasive particles are evenly distributed using a special coating technology, ensuring strong bonding, no particle shedding, and stable abrasive performance during grinding. It is widely used in automotive painting and repair, woodworking, metalworking, and other applications.
Product Introduction
Products Description
Reinforced Blue Film Backing
- Zirconia film sanding disc uses a flexible polyester film substrate with high tear resistance.
- Maintains polyester abrasive film disc stability under pressure, heat, and edge sanding conditions.
- Improves sanding consistency on both flat panels and curved surfaces.
- More durable than conventional paper-backed abrasive discs during continuous polishing work.
17-Hole Dust Extraction System
- Blue film polishing disc uses an optimized 17-hole airflow structure.
- Enhances dust collection efficiency during high-speed orbital sanding.
- Reduces abrasive clogging and maintains cleaner sanding performance over longer working cycles.
- Compatible with vacuum-assisted sanding systems commonly used in automotive and industrial finishing applications.
Stable Zirconia Cutting Performance
- Blue abrasive film disc uses premium zirconia alumina abrasive particles.
- Provides continuous cutting efficiency with controlled abrasive wear.
- Delivers faster defect removal while maintaining smooth surface quality before coating or polishing.
- Suitable for primer sanding, paint correction, and fine metal finishing applications.
Controlled Surface Finishing
- Zirconia blue abrasive film uses uniform abrasive grain coating technology.
- Produces even sanding patterns with reduced scratch inconsistency.
- Minimizes rework before painting, polishing, or coating processes.
- Widely used in automotive refinishing and precision industrial polishing environments.
High-Quality Substrate: The even distribution of abrasive particles on the Velcro-backed blue film disc promotes a smoother grinding process and effectively reduces potential damage to the workpiece. The grinding wheel uses top-grade polyester film as the substrate, offering excellent heat
resistance, tensile strength, and dimensional stability. It effectively withstands high temperatures and mechanical stress during grinding, thereby extending service life.
Stable Grinding: The back layer of the blue film polishing disc adopts a short-pile design to enhance adhesion between the sandpaper and the grinder while reducing direct friction with the workpiece. This design significantly improves wear resistance, ensuring long-term durability and stable performance.
Special Anti-Blocking Coating: The coating applied to the surface of the blue film abrasive disc has anti-blocking properties that prevent dust and debris from accumulating on the grinding surface. This not only prolongs the life of the abrasive film disc but also ensures uninterrupted material removal throughout the grinding process, guaranteeing consistent and high-quality results.
