Material
Pig Bristle
Pig Bristle 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
Pig bristle is an animal-derived tapered fill with natural variation in diameter, flagging and stiffness.
In a finished brush, Pig Bristle does not create a fixed stiffness by itself. Brush force and recovery come from the complete filament geometry and contact setting, not just the polymer name. Service conditions must also be considered.

Frequently Asked Questions
What are the key properties of Pig Bristle brush material?
Pig bristle is an animal-derived tapered fill with natural variation in diameter, flagging and stiffness. Direct data: Fiber diameter: 100–250 µm; Use temperature: up to 90°C; Brush stiffness: medium to firm; Liquid carrying: high; Wear behavior: good for polishing and application.
Where is Pig Bristle used in cleaning brushes?
Hand brushes, polishing and general natural-bristle cleaning where moderate stiffness and liquid carrying are useful.
How does filament geometry change Pig Bristle brush stiffness?
Pig Bristle 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 Pig Bristle be replaced by another material?
Compare Pig Bristle with Horsehair, nylon, PBT. Change material when wet stiffness, temperature, chemical resistance, conductivity, particle shedding, or surface marking becomes the limiting factor.
