Material
Flame Retardant Nylon
Flame Retardant Nylon 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
Flame-retardant nylon is a PA6, PA66 or related polyamide formulation engineered to meet a defined flammability test.
In a finished brush, Flame Retardant Nylon does not create a fixed stiffness by itself. Contact force and recovery depend on filament diameter, free trim, density, tuft pattern, and installed interference. Grade, moisture, temperature, and chemistry affect how that behavior changes in service.

Frequently Asked Questions
What are the key properties of Flame Retardant Nylon brush material?
Flame-retardant nylon is a PA6, PA66 or related polyamide formulation engineered to meet a defined flammability test. Direct data: Density: 1.15–1.35 g/cm³; Flammability: UL 94 V-0 grades available; Water absorption: 1–8% by PA grade; Use temperature: -20–120°C; Filament diameter: 0.15–1.20 mm.
Where is Flame Retardant Nylon used in cleaning brushes?
Cable-entry, enclosure, appliance and transport brushes built around a named flame-retardant resin grade.
How does filament geometry change Flame Retardant Nylon brush stiffness?
Flame Retardant Nylon 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 Flame Retardant Nylon be replaced by another material?
Compare Flame Retardant Nylon with Standard PA6/PA66, PPS, PEEK, flame-retardant polyester. Change material when wet stiffness, temperature, chemical resistance, conductivity, particle shedding, or surface marking becomes the limiting factor.
