Strip Brushes Fill Material

We can manufacture strip brushes using any of our available synthetic, natural or wire filaments. The type of material selected will depend upon the desired characteristics. Fill may be stiff or soft, thick or thin, repel or absorb water, chemical or heat resistant, flexible to a greater or lesser extent, and resistant to bending or abrasion.

Other filament characteristics include brush density and bristle length. Choosing a crimped filament, instead of a level or straight filament will provide a more dense brush appearance and a continuous, even brushing action. The crimp is measured by amplitude, depth of the crimp, frequency and number of crimps per inch. Level or straight bristles provide a lesser brush density appearance. The measurement of the exposed filament is known as the trim length and is the working strength of the brush.

The last filament characteristic is the trim shape, choices include:

• Flat is the most common shape used, unless there are specific reasons for using other shapes.
• Bevel reduces brush resistance and conforms to surface.
• Step is used for brushing irregular or uneven surfaces.
• Offset is a combination of trims which conforms to the surface.
