Material
DuPont Nylon Filament
DuPont Nylon Filament is selected from its stiffness, recovery, wear, wet-service, chemical, and temperature behavior. Brush stiffness depends on more than material. Filament size, exposed length, density, grade, and operating conditions all matter.
Material Overview
DuPont nylon filament is a polyamide brush-filament category covering wear-resistant PA6, PA66, PA610, PA612, and related nylon grades used in hand, strip, tube, and roller brushes.
In a finished brush, DuPont Nylon Filament does not create a fixed stiffness by itself. Working stiffness and recovery depend on filament size, free trim, density, tuft pattern, and contact. Grade and operating conditions determine how stable that behavior remains.

Frequently Asked Questions
What are the key properties of DuPont Nylon Filament brush material?
DuPont nylon filament is a polyamide brush-filament category covering wear-resistant PA6, PA66, PA610, PA612, and related nylon grades used in hand, strip, tube, and roller brushes. Direct data: Filament diameter: 0.075–2.50 mm; PA grades: PA6, PA66, PA610, PA612, PA12; Brush operating range: -20–120°C by grade; Water absorption: 0.3–10% by grade; Hardness: about Shore D 70–85.
Where is DuPont Nylon Filament used in cleaning brushes?
Hand, strip, tube, roller and machine brushes made with a named DuPont polyamide grade selected for the service.
How does filament geometry change DuPont Nylon Filament brush stiffness?
DuPont Nylon 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 DuPont Nylon Filament be replaced by another material?
Compare DuPont Nylon Filament with Verified PA6, PA66, PA610, PA612, PA12, PBT. Change material when wet stiffness, temperature, chemical resistance, conductivity, particle shedding, or surface marking becomes the limiting factor.
