Non-woven abrasives consist of a web of nylon fibers impregnated with abrasive grains bonded with synthetic resins. Non-Woven products are ideal for cleaning, blending, deburring, stripping, finishing and surface prep.
Recent innovations in fiber and resin technology have created new products for more finishing applications. Non-woven abrasives provide a controlled cut and consistent uniform finishes. These products are waterproof, washable, non-conductive, non-metallic, non-rusting and solvent resistant.
The size of the nylon fibers, and number of fibers compressed, provide a wide range of densities. Most hand pads, buff and blend discs and rolls are open weave, providing flexibility and conformity to the work-piece. Surface conditioning belts and discs will have a higher resin / abrasive content to provide better cut, life and finish. Clean and strip type discs are very rigid, with an open weave to reduce loading when cleaning mill scale or removing coatings. These are a great option compared to wire wheels.
Convolute and unitized wheels offer a density range between: 2 – soft open weave to 9 – hard durable weave. Wheel speed is a very important factor to maximize the performance of non-woven wheels.
Aluminum oxide grains are typically used for most deburring and blending applications, and silicon carbide is used to provide finer finishes. Ceramic grains are becoming more popular for some deburring and finishing applications.
The grit designations available include: extra-coarse(50 grit), coarse(60-80), medium(100-150), fine(180-220), very fine(240-360), super fine(400), ultra fine(600).
There are multiple forms of Non-Woven Abrasives:
- Hand Pads
- Flap Wheels
- Convolute Wheels
- Unitized Wheels & Discs
