Closed Cell Sponge Rubber
PVC-Nitrile
Overview
Blending polyvinyl chloride (PVC) with nitrile rubber (NBR), this closed-cell sponge rubber delivers a soft, lightweight, and chemical-resistant solution perfect for sealing, cushioning, and shock absorption. Renowned for its energy-absorbing properties and fine cell structure, it’s widely used across industrial, automotive, sports, and electrical applications.
Features
- Closed-cell construction provides air-, water-, and dust-tight sealing while suppressing moisture and contaminants.
- Excellent chemical and flame resistance, including UL 94 flammability listings and FMVSS-302 compliance in many grades.
- Superior energy absorption: fine cell structure offers cushioning for impact-prone applications.
- Wide temperature tolerance and resilience, suitable for various environments and thermal conditions.
- Fabrication-ready format: available in continuous rolls, sheets, or die-cut parts, with options for adhesive backing.
Benefits
