Our Aluminum Oxide Polishing Film Discs deliver high-precision surface finishing for metals, plastics, and composites. Designed as a cost-effective alternative to 3M 268XA, these discs feature uniform aluminum oxide abrasives on durable PET/TPU backings for exceptional flexibility and cutting performance. Ideal for automotive, aerospace, and industrial applications, they provide consistent results on flat or curved surfaces with dry, wet, or oil-based polishing. Available in multiple grits (400#-8000#) and sizes for versatile use.
Product Features
Precision-Graded Aluminum Oxide Abrasives
Uniformly dispersed abrasive particles ensure consistent material removal across all grit sizes (400#-8000#), delivering scratch-free finishes on sensitive surfaces.
Flexible TPU/PET Backing for Contoured Surfaces
The cushioned backing adapts perfectly to complex curves and edges while maintaining stability during high-speed polishing operations.
Multi-Environment Compatibility
Engineered for dry, water-cooled, or oil-based polishing, reducing heat buildup and extending disc lifespan in industrial production lines.
Batch-to-Batch Consistency
Strict quality control guarantees minimal variation between production lots, ensuring reliable performance for professional users.
Wide Material Compatibility
Effective on stainless steel, aluminum alloys, titanium, plastics, and resin composites - making it ideal for cross-industry applications.
