Material
PVC
PVC 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
PVC is polyvinyl chloride resin that compounded into rigid or flexible products; plasticizers and other additives control hardness, flexibility and several performance properties.
In a finished brush, PVC does not create a fixed stiffness by itself. The brush response is shaped by filament geometry, fill density, tuft pattern, and interference, then modified by moisture, temperature, and chemical exposure.
Material Properties

| Water absorption | below 0.1% |
| Shore hardness | A 70 to D 80 by compound |
| Profile diameter | 0.20–3.00 mm |
Brush Applications
For PVC, directly related brush structures include Strip Seal Brushes, Machine Table Brush Plates, Handheld Detail Brushes, and Wheel Brushes. Applications related to PVC include Dust Removal, Industrial Machine Cleaning, Brick, Tile & Building Material Machine Brush Use, and Mold Cavity Cleaning.

Frequently Asked Questions
What are the key properties of PVC brush material?
PVC is polyvinyl chloride resin that compounded into rigid or flexible products; plasticizers and other additives control hardness, flexibility and several performance properties. Direct data: Density: 1.35–1.45 g/cm³; Vicat softening range: 75–90°C; Water absorption: below 0.1%; Shore hardness: A 70 to D 80 by compound; Profile diameter: 0.20–3.00 mm.
Where is PVC used in cleaning brushes?
Wet sealing, light wiping and corrosion-resistant strip or board backing where load, heat and solvent exposure are moderate.
How does filament geometry change PVC brush stiffness?
PVC 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 PVC be replaced by another material?
Compare PVC with PE board, PP, elastomer, aluminum holder. Change material when wet stiffness, temperature, chemical resistance, conductivity, particle shedding, or surface marking becomes the limiting factor.
