Abrasive Types & Performance Highlights

1. 3M™ Trizact™ Microreplicated Belts (237AA / 305EA)

• Pyramid Microreplication: Multiple layers of micron-graded mineral break down evenly under pressure, continuously exposing fresh, sharp cutting edges.
• Cool & Predictable Finish: Runs significantly cooler than conventional abrasives, eliminating thermal blueing on stainless steel cutlery, medical instruments, and architectural fittings.

2. 3M Non-Woven Nylon Conditioning Belts

• Open-Web Architecture: Resists loading and heat buildup while blending handling scratches, oxide discoloration, and machine lines.
• Controlled Surface Uniformity: Imparts a professional linear satin grain across flat sheets, square tubing, and rounded contours.

3. Seamless Endless Wool Felt Belts

• Zero-Bump Seamless Design: Jointless ring design eliminates seam bounce and chatter marks during fine polishing on round tubing and flat plates.
• High Compound Carrier: Holds diamond paste, green rouge, or white buffing wax securely for true high-reflection mirror finishes.

Applications & Usage Recommendations

Engineered for standard 610x100mm (24"x4") belt sanders and grinders. Follow a systematic progression: begin with 3M Trizact belts (A65 to A16/A6) for scratch reduction; advance with Non-Woven belts for satin blending; conclude with Wool Felt belts charged with buffing compound for a streak-free mirror shine.
