Nylon PA

Nylon brush filament is a polyamide monofilament family; the exact PA grade controls water absorption, stiffness recovery, chemical response and heat behavior. Direct data: Density: 1.01–1.15 g/cm³ by PA grade; Melting range: 175–265°C by PA grade; Water absorption: 0.3–9% by PA grade and conditioning; Filament diameter: 0.08–2.50 mm; Brush operating range: -20–120°C.

General wet and dry cleaning, conveying, wiping and scrubbing where resilient contact and wear life are both important.

Nylon PA 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.

Compare Nylon PA with PP, PBT, PET. Change material when wet stiffness, temperature, chemical resistance, conductivity, particle shedding, or surface marking becomes the limiting factor.
