Floor Scrubber Disc Brush Selection

Nylon:

Nylon is the most durable synthetic bristle material with excellent abrasion resistance and bristle bend recovery resulting in a longer lasting brush.

Nylon provides very good chemical resistance and is an excellent bristle choice for general scrubbing.

Polypropylene:

Polypropylene is a synthetic bristle material with more durability than natural fibers and a little more economical than Nylon.

Polypropylene is highly resistant to chemicals, fungus, and bacteria. Ideal for general scrubbing, wet scrubbing, as well as stripping and re-coating.

Steel Wire:

Steel Wire bristles provide extremely aggressive stripping for rough concrete at an economical cost. 

Union: 

Union is an economical blend which is used in general floor buffing or polishing operations.

Bristle Stiffness:

Synthetic bristles offer the advantage of various sizes producing different stiffness levels. 

For instance, a .018 Nylon is very thin, only 18 thousandths thick, and therefore not very stiff, .070 Nylon is very large in diameter at 70 thousandths, and therefore very stiff. 

Larger numbers in front of the fiber type, mean stiffer, more aggressive the bristles.

Grit Size:

Silicon carbide grit is bonded to synthetic fibers to provide varying levels of scrubbing, aggressiveness. 

A 46 grit is a large size grit and very aggressive. 

500 grit size is very small and much less aggressive, similar to sandpaper types.  

The smaller the number for grit, the more aggressive the brush bristles will be.
