White Aluminum Oxide Yellow Sandpaper Rolls

White fused alumina (white aluminum oxide) has a hardness of 9.0 Mohs, and with superior sharpness compared to ordinary brown fused alumina, making it ideal for efficient grinding of metals, wood, and composite materials..
High-temperature calcination enhances the adhesion of abrasive grains, reducing shedding and extending service life.
The yellow polyester film backing is flexible and tear-resistant, suitable for curved and complex shapes. Its moisture resistance outperforms paper backing, making it ideal for humid environments.
Anti-static or oil-repellent coatings are added to reduce debris buildup, improving efficiency by 20% (compared to traditional sandpaper). Compliant with EU REACH and RoHS standards, free of benzene-based solvents, meeting environmental requirements for European and American markets.
Covers coarse grinding to fine polishing, meeting the demands of high-precision industries such as automotive and aerospace.
Large-scale production and automated processes reduce unit costs by 15-20% compared to European and American brands. Priced 10-15% lower than comparable products from brands like 3M and Norton, while maintaining similar performance (e.g., service life gap <5%).
Grit size tolerance controlled within ±5% (industry average ±10%), reducing rework rates.
