Material
Horsehair
Horsehair 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
Horsehair is natural animal hair whose tail and mane grades differ in stiffness; its scaled surface carries liquids and supports gentle finishing.
In a finished brush, Horsehair does not create a fixed stiffness by itself. Filament diameter, trim length, density, tuft layout, and installed contact determine working force, while grade and environment affect durability and recovery.

Frequently Asked Questions
What are the key properties of Horsehair brush material?
Horsehair is natural animal hair whose tail and mane grades differ in stiffness; its scaled surface carries liquids and supports gentle finishing. Direct data: Fiber diameter: 50–150 µm; Density: about 1.30 g/cm³; Use temperature: up to 80°C; Moisture behavior: absorbs water and softens slightly; Brush stiffness: soft to medium.
Where is Horsehair used in cleaning brushes?
Fine dusting, polishing, leather care and gentle interior cleaning on appearance-sensitive surfaces.
How does filament geometry change Horsehair brush stiffness?
Horsehair 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 Horsehair be replaced by another material?
Compare Horsehair with Boar bristle, goat hair, microfiber. Change material when wet stiffness, temperature, chemical resistance, conductivity, particle shedding, or surface marking becomes the limiting factor.
