Material
Rubber
Rubber is selected from its stiffness, recovery, wear, wet-service, chemical, and temperature behavior. Stiffness is set by the complete filament specification, including material, diameter, free trim, density, grade, and service conditions.
Material Overview
Rubber is a generic term for natural or synthetic elastomers that recover after deformation; it does not identify a usable compound by itself.
In a finished brush, Rubber does not create a fixed stiffness by itself. Contact performance comes from the filament geometry and installed setting; grade, moisture, heat, and chemistry determine how it performs over time.
Material Properties
| Hardness | 30–90 Shore A |
|---|---|
| Density | 0.9–1.4 g/cm³ |
| Use temperature | -30–120°C by elastomer |
| Compression set | 10–40% by grade |
| Water absorption | very low |

Frequently Asked Questions
What are the key properties of Rubber brush material?
Rubber is a generic term for natural or synthetic elastomers that recover after deformation; it does not identify a usable compound by itself. Direct data: Hardness: 30–90 Shore A; Density: 0.9–1.4 g/cm³; Use temperature: -30–120°C by elastomer; Compression set: 10–40% by grade; Water absorption: very low.
Where is Rubber used in cleaning brushes?
Squeegee, sealing and liquid-removal contact where elastomer hardness and chemical compatibility are known.
How does filament geometry change Rubber brush stiffness?
Rubber 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 Rubber be replaced by another material?
Compare Rubber with Silicone elastomer, TPE, PVC profile, PVA sponge. Change material when wet stiffness, temperature, chemical resistance, conductivity, particle shedding, or surface marking becomes the limiting factor.
