1. PET film as base paper guarantees high strength, anti-deformation, ultra even surface, heat-resistance, excellent flexibility and work pieces having smoother finish.2. Special-treated grains comply with EU standards. Special sand-planting technique realizes oriented grains evenly distributed. Sharp surface lead to superior cutting performance and consistent finish.3. Heat-resistant and high-strength base paper together with special bonding realizes persistent performance.4. Special anti-clog coating ensures good sanding dust removal and prevents clogging thus optimizes the product performance.5. Smoother surface than abrasive cloth. Better strength and dimension stability than abrasive paper. Waterproof and oil-resistant. Can be used wet or dry.
