Blue Film Abrasive Disc
Blue film abrasive discs use a special sanding process to evenly distribute high-quality zirconium corundum abrasives on a flexible and durable polyester film backing. The surface is coated with a special anti-blocking layer, making it ideal for metal plates, pipes, and wood processing, achieving a smooth surface and precisely removing burrs.
Product Introduction
Products Description
Reinforced Blue Polyester Film Backing
- High-strength PET film substrate with flexible structure.
- Resists tearing and maintains stability during edge and contour sanding.
- Ensures uniform sanding marks across curved panels and flat surfaces.
- Performs more consistently than paper-backed abrasives in long-cycle sanding work.
Wet & Dry Dual Performance Behavior
- Resin-bonded zirconia abrasive structure with water-resistant coating.
- Supports both dry aggressive sanding and wet fine finishing applications.
- Provides flexibility for multi-stage surface preparation using a single abrasive system.
- Commonly used in automotive paint repair and precision metal finishing.
Controlled Finishing Stability
- Uniform abrasive grain distribution technology.
- Maintains consistent cutting behavior throughout disc lifespan.
- Reduces rework caused by uneven scratch depth or inconsistent sanding marks.
- Suitable for primer leveling, paint correction, and pre-polishing processes.
Balanced 7-Hole Dust Management System
- Optimized 7-hole airflow distribution design.
- Maintains stable dust evacuation without sacrificing sanding contact area.
- Reduces abrasive loading while keeping surface finishing smooth and controlled.
- Suitable for orbital sanding machines used in automotive and industrial finishing environments.
Wet and Dry Applications: Our blue polyester abrasive discs are suitable for both dry and wet grinding. In dry applications, they quickly remove stains and uneven surfaces from the workpiece. In wet applications, they reduce heat and dust buildup, enhancing grinding efficiency and improving
surface finish.
Durable and Resilient Structure: Blue film sanding discs are resistant to tearing and wear, maintaining their integrity even under high-pressure grinding. This durability improves grinding efficiency, reduces disc replacements, and saves time and cost.
Powerful Material Removal: The discs deliver strong cutting action for removing hard coatings, rust, or rough surfaces. They efficiently remove excess material from metal, wood, or other substrates, ensuring fast and precise results.
Versatile Applications: These blue film abrasive discs can be used on a variety of materials, including metals (steel, aluminum, brass), wood (hardwood and softwood), and plastics.

FAQ
01. What is the main difference between blue film discs and paper sanding discs?
Blue film discs use a polyester film backing, which provides higher tear resistance, more stable cutting performance, and longer service life compared to traditional paper-based abrasives.
02. Can this disc be used for both wet and dry sanding?
Yes. The resin-bonded structure and film backing allow stable performance in both wet sanding and dry sanding applications.
03. Is this product suitable for automotive refinishing work?
Yes. It is commonly used in automotive body repair for primer sanding, paint preparation, and clear coat finishing.
04. Can it replace Deerfos SA331 series products?
Yes. It is designed as a performance-equivalent alternative to Deerfos SA331 film abrasive discs in similar applications.
