In semiconductor chips with nanometer-scale circuit patterns and optical lenses requiring hair-level flatness, surface finishing precision has become the “invisible threshold” for product performance. Traditional sandpaper, with its short lifespan and low accuracy, has long restricted efficiency improvements in precision processing industries.
Feilong Polyurethane Equipment addresses this challenge through “abrasive embedding technology”—embedding diamond abrasives into a polyurethane matrix. This innovation extends the service life to 4–6 times that of traditional sandpaper. Combined with water-resistant characteristics, it enables three times longer continuous operation in automated production lines.
Traditional Sandpaper vs. Polyurethane Polishing Pads: Core Performance Comparison
- Service Life: Traditional sandpaper ≈ 200 uses/piece; Feilong polishing pad: 800–1,200 uses/piece
- Precision Control: Sandpaper ±5 μm fluctuation; Polyurethane pad: ±0.5 μm stability
- Environmental Resistance: Sandpaper is moisture-sensitive; polyurethane pad is acid/alkali-resistant and supports wet polishing
Product Advantages: Precision Through Material & Process Innovation
Feilong applies a three-dimensional logic chain—Material Formulation → Microstructure → Process Adaptation—to build differentiated technical advantages:
- Material Engineering Hardness gradient adjustment (Shore hardness 30–100, continuously adjustable) Functional additives: cerium oxide increases polishing speed by 30%, zirconia reduces surface roughness to Ra < 0.2 nm Environmental durability: <0.5% weight change after 24 hours in 10% HCl solution
- Microstructure & Design Foam pore structure (20–50 μm) for better polishing slurry flow, improving processing speed by 40% Grooving (10P/15P/20P/30P) & perforation (2 mm multi-angle arrangement) for various applications Sandwich structure (elastic polyurethane foam + aluminum core) achieves dynamic balance accuracy of 0.002 mm, eliminating eccentric vibration during high-speed rotation
Technical Highlights
- Abrasive retention solution: Diamond abrasives embedded in polyurethane extend life up to 6× traditional sandpaper
- Full-process adaptability: Grit size 60–5000 mesh, hardness 30–95°, covering rough to fine polishing
- Environmental adaptability: Acid/alkali resistance, washable, reusable, 80% less wet-grinding dust
