Material
Sisal Fiber
Sisal Fiber is selected from its stiffness, recovery, wear, wet-service, chemical, and temperature behavior. Material name alone is not enough to set stiffness; we also need filament diameter, free trim, density, grade, and working conditions.
Material Overview
Sisal is a leaf fiber from Agave sisalana, valued for strength and absorbency in traditional fiber applications.
In a finished brush, Sisal Fiber does not create a fixed stiffness by itself. Working stiffness and recovery depend on filament size, free trim, density, tuft pattern, and contact. Grade and operating conditions determine how stable that behavior remains.

Frequently Asked Questions
What are the key properties of Sisal Fiber brush material?
Sisal is a leaf fiber from Agave sisalana, valued for strength and absorbency in traditional fiber applications. Direct data: Fiber diameter: 100–300 µm; Density: about 1.45 g/cm³; Use temperature: up to 100°C; Brush stiffness: medium to firm; Compound carrying: high.
Where is Sisal Fiber used in cleaning brushes?
Rough buffing, polishing and surface preparation of wood and metal with a firm natural fiber.
How does filament geometry change Sisal Fiber brush stiffness?
Sisal Fiber 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 Sisal Fiber be replaced by another material?
Compare Sisal Fiber with Cotton, felt, abrasive nylon. Change material when wet stiffness, temperature, chemical resistance, conductivity, particle shedding, or surface marking becomes the limiting factor.
