Material
PA610 Nylon
PA610 Nylon is selected from its stiffness, recovery, wear, wet-service, chemical, and temperature behavior. For brush stiffness, do not give only the material name. Filament diameter, free trim, density, grade, and service conditions must be specified together.
Material Overview
PA610 is a long-chain polyamide filament whose longer hydrocarbon segment generally reduces water uptake relative to shorter-chain nylon grades.
In a finished brush, PA610 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 PA610 Nylon brush material?
PA610 is a long-chain polyamide filament whose longer hydrocarbon segment generally reduces water uptake relative to shorter-chain nylon grades. Direct data: Density: 1.07–1.09 g/cm³; Melting point: 210–220°C; Water absorption at saturation: 2–3%; Wet stiffness retention: about 65–75%; Filament diameter: 0.08–2.50 mm.
Where is PA610 Nylon used in cleaning brushes?
Wet-process rollers, tube brushes and cleaning heads that need lower moisture uptake than PA6 or PA66.
How does filament geometry change PA610 Nylon brush stiffness?
PA610 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 PA610 Nylon be replaced by another material?
Compare PA610 Nylon with PA66, PP, PBT. Change material when wet stiffness, temperature, chemical resistance, conductivity, particle shedding, or surface marking becomes the limiting factor.
