Abrasive Nylon

Tanis has four abrasive nylon filament types including silicon carbide, silicate, aluminum oxide and our exclusive CeramiX™ filament. An abrasive filament is a unique type of filament that combines nylon and an abrasive grit which is dispersed uniformly and impregnated through the nylon thread base in a special formulation to deliver durability, chemical resistance, strength and stiffness, even when wet. Abrasive filament provides sharp cutting edges of grit, which can be held firmly against any surface, no matter how irregular its shape. As the brush moves against the surface, the flexible filaments bend at various angles to fit the surface contours, allowing the cutting edges of the grit to have continuous contact. Abrasive filaments are as aggressive on the sides as the tips.

Abrasive filament is most often made with the highest-quality nylon 6.12 for use in wet or dry applications. Nylon 6 or Nylon 6.6 is suitable for dry applications and can be treated against thermal degradation. Filaments are available in a broad combination of grit sizes (2000 grit to 46 grit), loading (20% to 40%) and diameters (.012” to .060”).

CeramiX™

This exclusive new filament is a tough, hard and self-sharpening abrasive grain with a durable crystalline structure that increases the life of the product. The abrasive grain mineral is a proprietary product of 3M™. The mineral grain in CeramiX™ wears away in smaller chunks leaving more mineral available to continuously work on the metal surface. Available in 220, 180, 120 and 80 grit sizes.

CeramiX™ provides superior benefits including enhanced cutting action of three-to-five times faster on ferrous metal surfaces compared to traditional abrasive nylons, increasing throughput, uniform filament wear and distribution of abrasive grain providing consistently smooth surface finishes and performs well under high stress and heat.

Silicon Carbide

Silicon carbide is harder, sharper and more aggressive than aluminum oxide and because its more durable it is preferred for finishing ferrous metals. Silicon carbide is generally available in 500 to 46 grit and diameter ranges from .018” to .060”. Benefits of this filament type include uniform wear and distribution of abrasive grain, consistently smooth finish, less filament breakage compared to wire, increased throughput and a longer brush life with lighter work pressure.

Silicate

Silicate is a fine grade abrasive filament for fine finishing and cleaning. It is available in .008” diameter and 2000 grit for micro-finishes used most commonly in miniature twisted-in-wire brushes.

Aluminum Oxide

Aluminum oxide is more impact-resistant compared to silicon carbide and is less likely to fracture and is preferred for finishing soft metals or other materials where a smooth finish is required. Aluminum oxide is generally available from 600 to 80 grit and diameter ranges from .012” to .040”.
