Industry Absorbent PVA Sponge Roller Washing Brushes For Cleaning Glass
The PVA Sponge Roller is a high-performance tool designed for precision cleaning, polishing, and liquid application. Made from polyvinyl alcohol (PVA), this ultra-absorbent roller excels in wet environments, efficiently soaking up oils, coolants, and solvents without deteriorating. Its open-cell structure ensures consistent material application, making it ideal for paint, adhesives, and chemical treatments.
With excellent wear resistance and a non-abrasive surface, it delivers a scratch-free finish on delicate materials like glass, metal, and automotive surfaces. The durable sponge construction allows for repeated use, even in high-pressure applications. Compatible with standard roller frames, it’s widely used in industrial cleaning, printing, and surface preparation.
Product Overview of PVA Roller Sponge
Structure:Absorbent Layer: White PVA sponge with open-cell structure for high liquid retention and controlled release.
Core: Rigid PVC tube providing structural stability and seamless integration into automated cleaning systems.
Design: Cylindrical shape with uniform thickness to ensure consistent contact with PCB surfaces.
Key Traits: Non-abrasive, chemically resistant, and lint-free to prevent contamination.
Material Advantages of PVA Roller Sponge
| Component | Material Properties |
| PVA Sponge | - High absorbency (retains water, solvents, or cleaning agents). |
| | - Resistant to oils, acids, and alkalis. |
| | - Reusable and durable under repeated compression. |
| PVC Tube | - Lightweight yet rigid for smooth rotation. |
| | - Corrosion-resistant and compatible with most industrial cleaning fluids. |
Key Applications of PVA Roller Sponge
Precision Cleaning – Used for removing contaminants, dust, and residues from sensitive surfaces like optical lenses, electronic components, and medical devices.
Printing & Coating – Ideal for applying even ink, paint, or adhesive coatings in printing machines, panel manufacturing, and automated coating systems.
Polishing & Buffing – Provides a scratch-free finish on metals, plastics, and composites in automotive, aerospace, and jewelry industries.
Liquid Absorption & Transfer – Efficiently absorbs and dispenses liquids (e.g., solvents, oils) in cleaning, chemical processing, and semiconductor wafer treatments.
