Material
Anti-static Filament
Anti-static Filament is selected from its stiffness, recovery, wear, wet-service, chemical, and temperature behavior. The same material can produce different stiffness, so filament diameter, trim length, density, grade, and service conditions must also be defined.
Material Overview
Anti-static filament controls charge accumulation through dissipative polymer, conductive additives, or conductive surface treatment.
In a finished brush, Anti-static Filament does not create a fixed stiffness by itself. Filament diameter, trim length, density, tuft layout, and installed contact determine working force, while grade and environment affect durability and recovery.
Material Properties
| Surface resistance | 10⁶–10⁹ ohms |
|---|---|
| Filament diameter | 0.10–1.00 mm |
| Charge decay target | below 2 seconds in ESD-controlled designs |
Brush Applications
For Anti-static Filament, directly related brush structures include Roller and Conveyor Brushes, Strip Seal Brushes, Handheld Detail Brushes, and Tube & Pipe Bore Brushes. Applications related to Anti-static Filament include Brick, Tile & Building Material Machine Brush Use, Carpet Machine Cleaning, Mold Cavity Cleaning, and Dust Removal.

The word anti-static alone cannot prove ESD protection, ATEX suitability, cleanroom suitability or lifetime conductivity.
Frequently Asked Questions
What are the key properties of Anti-static Filament brush material?
Anti-static filament controls charge accumulation through dissipative polymer, conductive additives, or conductive surface treatment. Direct data: Surface resistance: 10⁶–10⁹ ohms; Filament diameter: 0.10–1.00 mm; Brush operating range: -20–100°C; Charge decay target: below 2 seconds in ESD-controlled designs.
Where is Anti-static Filament used in cleaning brushes?
Static-control contact on paper, film, textile and electronics lines when the complete brush has a defined grounding path.
How does filament geometry change Anti-static Filament brush stiffness?
Anti-static Filament changes brush stiffness through filament diameter, free trim, density, crimp, and contact. Use finer filament and longer trim for conformable contact; use coarser filament, shorter trim, or higher density for stronger displacement or cutting.
When should Anti-static Filament be replaced by another material?
Compare Anti-static Filament with Conductive nylon, carbon fiber, metal fiber, ordinary nylon. Change material when wet stiffness, temperature, chemical resistance, conductivity, particle shedding, or surface marking becomes the limiting factor.
