PSA Abrasive Film Disc
The PSA abrasive film discs are made of high-quality zirconium aluminum oxide particles for enhanced performance and cutting power. The PET polyester film backing features anti-clogging technology and a flexible substrate, making the abrasive film discs durable, strong, and stable during cutting. They are suitable for grinding paint, wood, metal, and other materials.
Product Introduction
Products Description
Fast Cutting Performance
- PSA zirconia film sanding disc uses premium zirconia abrasive grains with a high-density coating.
- Delivers aggressive and stable cutting performance during continuous sanding.
- Reduces sanding time and improves production efficiency in automotive refinishing and metal surface preparation.
- Engineered to achieve performance comparable to Deerfos SA331 sanding systems.
Durable PET Film Backing
- Flexible polyester film backing with high tensile strength.
- Provides better edge retention and prevents tearing during machine sanding.
- Ensures more uniform scratch patterns and extends disc service life compared with traditional paper discs.
- Suitable for high-speed orbital sanding and demanding industrial finishing operations.
Anti-Clogging Surface Treatment
- Blue zirconia sanding disc with special anti-loading stearate coating technology.
- Effectively minimizes dust buildup and surface clogging during sanding.
- Maintains consistent cutting efficiency and reduces frequent disc replacement.
- Especially effective for sanding primer, filler, paint, and soft metal surfaces.
PSA Adhesive Backing System
- Zirconia film sanding disc with strong pressure-sensitive adhesive (PSA) attachment design.
- Allows quick disc installation and secure adhesion during operation.
- Improves workflow efficiency and minimizes downtime in batch sanding applications.
- Widely used in automotive repair shops, furniture manufacturing, and industrial sanding production lines.
Improved Pressure-Sensitive Adhesive (PSA) Technology: Our PSA blue film discs feature an enhanced PSA layer. This adhesive forms a strong bond with the sanding pad, ensuring the disc remains firmly fixed during high-speed sanding operations and eliminating the risk of slipping.
The unique adhesive formulation also allows for easy disc removal without leaving any residue on the sanding pad, a common issue with traditional adhesives.
Flexible Film Base: The base of the PSA abrasive film discs is made of flexible material, allowing the disc to adapt easily to complex and irregular surfaces. It can conform to curves, edges, and uneven areas, ensuring even sanding across the entire workpiece. The elastic properties of the film also help absorb vibrations during sanding, resulting in smoother operation and a better surface finish.
Available in a Variety of Grit Sizes: Flexible blue film sanding discs are available in a wide range of grit sizes, from very coarse to ultra-fine, allowing you to customize your sanding process. Coarse grits (e.g., P40–P60) are ideal for quick material removal, such as leveling rough surfaces or removing thick layers of paint or rust. Medium grits (P80–P180) are used for general sanding and surface preparation. Fine grits (P240–P600) and ultra-fine grits (P800 and above) are suitable for mirror finishes or super-smooth surfaces.
