Non Woven Abrasives: Complete Guide to Products, Types and Applications
Non woven abrasives are widely used in metal finishing, stainless steel fabrication, surface preparation and polishing. They help remove light scratches, clean surfaces, blend weld marks and achieve a consistent finish without removing excessive material.
Unlike conventional coated abrasives, non woven abrasives are made from a three dimensional network of synthetic fibres bonded together with abrasive grains and resin. This open structure allows air to circulate through the material, helping reduce heat buildup and providing a more controlled finishing process.
At Flap Craft, we offer a range of non woven abrasive products designed for different finishing requirements, from weld blending and surface cleaning to fine polishing and finishing operations.
What Are Non Woven Abrasives?
Non woven abrasives are flexible abrasive materials manufactured using synthetic fibres, abrasive grains and bonding agents. The fibres form an open, interconnected structure that holds the abrasive grains throughout the material.
This construction allows the abrasive to work evenly across the surface while providing flexibility and consistent finishing performance.
Non woven abrasives are commonly used on stainless steel, mild steel, aluminium and other metals. Depending on the product type and abrasive grade, they can be used for cleaning, deburring, blending, surface preparation and achieving decorative finishes.
Benefits of Non Woven Abrasives
Non woven abrasives offer several advantages for industrial finishing applications.
- Consistent surface finishing: Their open structure helps produce uniform finishes across different workpiece shapes.
- Reduced heat buildup: The porous material promotes airflow during operation, helping minimise heat accumulation.
- Flexible surface contact: Non woven abrasives can adapt to contours, edges and irregular surfaces.
- Controlled material removal: They are suitable for applications where surface refinement is important without aggressive grinding.
- Effective weld blending: Selected grades can help blend weld marks and prepare surfaces for subsequent finishing.
- Versatile applications: Different product formats can be used with hand tools, angle grinders, straight grinders, belt machines and other compatible equipment.
Types of Non Woven Abrasive Products by Flap Craft
1. Non Woven Flap Wheel
Non woven flap wheels are designed for surface finishing, cleaning and blending applications. They consist of non woven abrasive material arranged in a flap configuration, allowing the wheel to maintain contact with the workpiece during operation. They are suitable for finishing curved surfaces, tubes, profiles and fabricated metal components where a uniform appearance is required. Common applications include stainless steel finishing, weld blending, light deburring, removal of surface imperfections and preparation before polishing.
2. Unitised Polishing Wheel
Unitised polishing wheels are made from compressed layers of non woven abrasive material bonded into a solid, unified structure. This construction provides greater dimensional stability than softer, less compact abrasive materials. They are used for precision finishing, deburring, edge refinement and polishing applications where control and consistency are important. Unitised polishing wheels are commonly used on small metal components, precision parts, medical instrument components and other applications requiring controlled surface treatment. The appropriate wheel density and abrasive grade depend on the material, the desired finish and the amount of material that needs to be removed.
3. Unitised Non Woven Disc
Unitised non woven discs are compact abrasive discs designed for controlled finishing, deburring and edge treatment. Their solid construction helps maintain the disc shape during use and supports consistent contact with the workpiece.
These discs are useful for removing minor burrs, blending machining marks and finishing metal components without the aggressive cutting action of conventional grinding discs. They are commonly used in metal fabrication, precision engineering, tool manufacturing and general industrial finishing. Choosing the correct density and grade helps achieve the required balance between material removal, surface smoothness and finishing time.
4. Unitised Mop Wheel
Unitised mop wheels combine the finishing characteristics of non woven abrasives with a structured wheel design suitable for repeatable surface treatment. They are used for finishing, blending and refining surfaces on metal components. Depending on the wheel specification, they can help remove light imperfections and create a more consistent surface appearance. Typical applications include stainless steel components, fabricated parts, metal profiles and industrial products that require controlled finishing.
5. Non Woven Hand Pads and Rolls
Non woven hand pads and rolls are versatile abrasive materials used for manual surface preparation and finishing. They are suitable for applications where precision, flexibility and direct control are required. Hand pads are useful for cleaning surfaces, removing light oxidation, blending minor scratches and preparing metal before painting or coating. Non woven rolls allow users to cut the material to the required length or shape, making them practical for workshops and production environments with varied finishing needs. These products are commonly used for stainless steel maintenance, general metal cleaning, paint preparation, surface scuffing and finishing hard to reach areas.
6. Surface Conditioning Belts
Surface conditioning belts are non woven abrasive belts designed for use with compatible belt grinding and finishing machines. They are used to clean, blend and refine metal surfaces while maintaining a consistent finishing pattern. These belts are particularly useful in stainless steel fabrication, tube finishing, sheet metal processing and industrial manufacturing. Common applications include blending weld marks, removing light surface imperfections, preparing metal for polishing and producing uniform brushed finishes. Surface conditioning belts are available in different abrasive grades and specifications to suit various materials and finishing requirements.
7. Surface Conditioning Velcro Disc
Surface conditioning Velcro discs are non woven abrasive discs with a hook and loop backing system. This attachment method allows quick disc changes, making them convenient for finishing operations that require frequent grade changes. They are used for surface cleaning, scratch blending, light deburring and preparing metal surfaces for further finishing. These discs are suitable for compatible random orbital sanders and other machines designed for hook and loop abrasive discs. In stainless steel fabrication, surface conditioning Velcro discs can help refine surface imperfections and create a more uniform finish before subsequent polishing stages.
8. Non Woven Rolloc Disc
Non woven Rolloc discs are compact surface conditioning discs designed for quick attachment to compatible Roloc style backing pads and power tools. Their convenient mounting system makes them useful for small area finishing and applications that require frequent tool changes. They are commonly used for weld blending, cleaning, light deburring and finishing metal components in areas that may be difficult to reach with larger abrasives. Non woven Rolloc discs are suitable for maintenance work, automotive component finishing, fabrication workshops and general metalworking. They are particularly useful when operators need greater control over localised finishing areas, edges and complex component shapes.
