Product Introduction: F-weight Cotton-Polyester Woven Base Fabric with PVA Impregnation

Product Overview

Our F-weight abrasive products combine a robust cotton-polyester woven base fabric with advanced PVA (Polyvinyl Alcohol) impregnation technology, delivering superior performance in medium-to-heavy duty grinding and polishing applications. Designed for industrial machinery and demanding environments, this solution balances strength, flexibility, and durability to optimize productivity while minimizing downtime.

Key Features & Benefits

F-weight Base Fabric

Medium-to-Heavy Strength: With a grammage of 170–250 g/m² , F-weight fabric provides higher tensile strength and abrasion resistance than standard D-weight (≈130 g/m²) while maintaining better flexibility than X-weight (>250 g/m²).

Cotton-Polyester Blend: A 65% polyester + 35% cotton mix ensures a balance of rigidity (from polyester) and softness (from cotton), ideal for conforming to curved surfaces without compromising durability.

PVA Impregnation Technology

Enhanced Heat Dissipation: PVA’s micro-porous network channels heat away from the workpiece, preventing thermal damage to both the material and the abrasive.

Self-Cleaning Properties: The hydrophilic nature of PVA attracts and retains debris, allowing the abrasive to maintain consistent cutting efficiency even in high-dust environments .

Flexible Bonding: PVA forms a resilient, elastic film that holds abrasives securely while enabling the product to adapt to irregular surfaces, reducing the risk of scratches or uneven finishes.

Chemical Resistance: PVA is resistant to oils, solvents, and moisture , extending the product’s lifespan in harsh industrial settings.

Performance Advantages

Longevity: The combination of F-weight fabric and PVA impregnation results in 2–3 times longer service life compared to conventional abrasive products under similar conditions.

Consistent Finish Quality: The elastic PVA matrix ensures uniform abrasive distribution, minimizing surface imperfections and achieving mirror-like finishes on metals, composites, and wood .

Versatility: Suitable for both dry and wet grinding , making it adaptable to diverse applications and environments.

Applications

Metal working: Deburring welds, removing rust/paint, and finishing stainless steel, aluminum, or titanium alloys.

Wood working: Profiling edges, sanding hardwoods, and preparing surfaces for coatings.

Composite Processing: Polishing carbon fiber, fiberglass, or acrylic materials without delamination.

Stone & Glass: Smoothing marble, granite, or glass edges with minimal chipping .
