Hook and Loop Round Sponge Sanding Disc Wet Dry Flexible Sponge Sandpaper for Car Paint Wood Plastic Metal Polishing

Our round sponge sanding disc is made of high resilience soft sponge substrate tightly bonded with premium aluminum oxide abrasive grains via advanced resin glue technology. It comes with standard hook & loop backing, allowing quick installation and convenient replacement on random orbital sanders without extra adhesive tape. The flexible sponge base can closely fit curved, contoured and irregular workpiece surfaces, effectively preventing excessive cutting and deep scratches on delicate materials. Designed for both wet and dry sanding applications, special anti-clog coating reduces abrasive loading from paint dust and wood chips to prolong overall service life greatly. Available in common diameters such as 3 inch, 5 inch and 6 inch with full grit range from 180# up to 3000# to satisfy rough grinding and fine mirror polishing needs. These sponge discs are widely applied in automotive paint refinishing, putty leveling, wood furniture finishing, plastic trimming, handicraft processing and non-ferrous metal surface polishing, delivering consistent fine finishing effect for daily industrial and DIY processing.

• Manufactured with ultra-soft sponge material as buffer layer, this sanding pad can evenly disperse partial grinding pressure when polishing various workpieces so as to produce remarkably smooth surface finish after sanding treatment.
• Its moderate soft grinding property prevents excessive cutting on workpiece surface, which can effectively reduce the occurrence of deep scratches and obvious grinding marks on automotive paint, solid wood and plastic products.
• The substrate adopts compact high-density sponge with stable internal structure and outstanding resilience, keeping complete shape without easy deformation under long-term continuous extrusion and repeated friction.
• This round sponge sanding disc realizes flexible switching between dry grinding and water wet polishing according to construction needs, perfectly matching different processing techniques of fine finishing and coarse leveling.
