SiC / Al2O3 Abrasive Nylon Filament (Bulk)

Description

The SiC / Al2O3 Abrasive Nylon Filament (Bulk) is raw abrasive nylon feedstock for brush makers, consisting of nylon loaded with silicon carbide (SiC) or aluminium oxide (Al2O3) grit. Supplied as filament for manufacturing abrasive brushes, the grit is distributed through the nylon so cutting ability is maintained as the filament wears. The abrasive load runs 20 to 40%; round filament is available in grit 36–500 (SiC) or 80–600 (Al2O3), and rectangular filament in grit 80, 120, 180, and 320. Produced at our Yuantan factory cluster, the abrasive type, load, filament cross-section, and grit can be specified for your brush production.

This bulk abrasive nylon monofilament is feedstock for brush manufacturing, not a finished brush — silicon carbide (SiC) or aluminium oxide (Al2O3) grit is loaded into the nylon at 20–40% abrasive load, with round cross-section available in 36–500 grit and rectangular cross-section in 80, 120, 180 and 320 grit. Brush makers select cross-section and grit to match the finished product's cutting action.

SiC generally cuts more aggressively on hard materials; Al2O3 is a common general-purpose abrasive. Tell us your target application and finished brush type and we'll recommend a grit, cross-section and abrasive load.

Frequently asked questions

Is this sold as a finished brush or raw filament?

Raw bulk filament — this is feedstock for making brushes, not a finished product. If you need a finished abrasive nylon cup brush or wheel, see our 4 in Nylon Abrasive Wire Cup Brush or Abrasive Nylon Wheel Set.

What's the difference between SiC and Al2O3 abrasive?

Silicon carbide (SiC) generally cuts more aggressively on hard materials; aluminium oxide (Al2O3) is a versatile general-purpose abrasive. Tell us your target material and we'll recommend one.

What abrasive load percentage should I order?

20–40% is the available range — higher load cuts more aggressively but can reduce filament flexibility. Tell us your finished brush's intended use and we'll recommend a load.
