Microfine Sponge Sandpaper

About: Product Description

Microfine Sponge Sandpaper is DMS's flagship high-efficiency precision grinding consumable. Its highlights include uniform scratch patterns, excellent clog resistance, and extended service life. It utilizes premium silicon carbide abrasives with a fabric + sponge composite backing. The open-coat abrasive is bonded to a fleece backing. Its flexible woven structure allows free passage of water and air, enabling both dry and wet grinding. It effortlessly handles contour and curved surface grinding, balancing efficiency with surface finish quality.

How Does the Material Achieve Efficient Fine Grinding?

The advantage stems from premium materials combined with scientific processes. The abrasive uses high-purity, premium silicon carbide with uniform particles and stable cutting force. During grinding, it creates fine, consistent scratches, avoiding uneven depths in localized areas, laying a solid foundation for subsequent polishing operations.

The composite structure combines fabric and sponge layers. The fabric layer enhances overall abrasion resistance and tear strength, while the sponge layer provides exceptional flexibility. This allows the product to conform closely to contours and curved surfaces. The flexible weave structure incorporates strategic gaps, permitting free passage of water and air. This dual-use capability for wet and dry grinding reduces debris buildup, significantly improves clog resistance, and substantially extends product lifespan.

What precision grinding applications is it suitable for?

DMS's Microfine Sponge Sandpaper, with its uniform scratch pattern, flexible conformability, and wet/dry versatility, is widely used in precision grinding processes across automotive, furniture manufacturing, and 3C electronics industries.

Additionally, it excels in scenarios demanding high grinding precision, such as instrument lacquer finishes, hardware fittings, and mold contours. Its dual-use capability accommodates diverse processing needs.

FQA

About: What precautions should be taken during use?

Q: What should be noted to ensure grinding effectiveness and extend product lifespan?

A: The product features a backing pad adhesive bond and must be used with a corresponding backing pad tray to ensure secure adhesion, preventing detachment or slippage during grinding.

Suitable for both dry and wet grinding. Dry grinding is ideal for precise material removal, while wet grinding requires compatible water or grinding fluid to enhance clog resistance and refine scratches.

Q: What are the grinding requirements?

A: Adjust pressure according to the workpiece's curvature and hardness. The sponge's flexibility allows natural conforming to surfaces—avoid excessive force to prevent surface damage.

Promptly clean residual abrasive particles from the surface and gaps after grinding to maintain the open-cell structure.

Q: How should it be stored?

A: Store flat in a dry, well-ventilated area away from high temperatures and humidity to prevent loss of backing adhesive strength and sponge deterioration. Avoid contact with sharp objects that may scratch the abrasive surface.
