As the demands for improved finishes increase—and companies like Ford announce that the F-150 truck is moving to aluminum as the primary material—fabricators need abrasives solutions that streamline their operations. Non-woven abrasives can provide an excellent solution.
What Is Non-Woven?
In its simplest form, non-woven it is an abrasive product where the base is an open nylon filament web to which abrasive grain is bonded.
The advantages of non-woven abrasives are many. It is resilient, comfortable, waterproof, non-loading and non-rusting. This allows for the following advantages when used on portable grinding, sanding and finishing operations:
-A controlled cut with minimal stock removal
-A predictably consistent, uniform finish
-Ease of use and reduced operator training
-Increased safety over other grinding methods
-Ability to be used on irregular surfaces.
Next-Generation
Non-wovens have been around for more than 50 years and have been used primarily for cleaning and finishing. Recent advancements in all of the product components have not only improved the core applications but also extended the performance into other metal fabrication applications.
Non-woven backing: An expansion in the porosity of the fibers from very open to very tight has provided products that work across more applications and materials. Non-wovens now offer strong performance in light metal removal, deburring, blending and finishing, and they excel on material where loading is an issue.
Bond chemistry: Previously, when the resin overheated, it would often smear the work surface. New bond chemistry has virtually eliminated this.
Grain technology: Once the domain of fine grit, low-cost aluminum oxide and silicon carbide abrasives, the new resins and nylon mesh now allow for integration of both coarser grits and premium abrasives. Extra-coarse (36-40) and coarse (50-80) are now used for stripping and light metal removal.
High-performance grains such as ceramic alumina with its ultra-sharp, micro crystal structure, and agglomerated grains that allow coarse grits to be built out of finer particles, are revolutionizing the cut rate and life of all non-woven products.
