Nylon PA66 Filament for Industrial Roller Brush Nylon Filament PA66 is common filament material for making industrial brushes to carry out polishing, grinding, sanding and finishing tasks in the production. Industrila Brush Filament has better wear resistance and impact resistance to polish the workpieces without filament breaking situation. Its high temperature resistance of 263 centigrade to makes industrial roller brushes work efficiently in heat temperature working environment, in which the Brush Bristle PA66 does not deform. Strong anti-corrosion ability can bear any acid-base environment and the filkament color does not fade.
