What Is Closed Cell PVC Foam?

Polyvinyl Chloride PVC foam is a closed-cell PVC sponge foam designed to provide an economical solution for sealing light, air, moisture, dust and vibration. Its soft closed-cell structure allows the foam to compress and conform to irregular surfaces while maintaining reliable sealing performance.

By adjusting density, hardness, resilience and other properties, PVC sponge foam can deliver different performance levels for specific application scenarios. Typical customizable density range is 80kg/m³ to 500kg/m³, and hardness can be customized from Shore 00 5° to 99° according to the required sealing force and application environment.

Closed cell PVC foam is highly suitable for vehicle body vibration damping, door and window sealing, water tank sealing, HVAC sealing, cushioning for electronic products, appliance sealing, outdoor lighting protection and custom foam gasket applications.

Applications of PVC Sponge Foam

• Door and window sealing strips.

• Truck, cab and vehicle body seals.

• HVAC sealing and air-conditioning insulation parts.

• Appliance sealing and vibration damping pads.

• Die-cut gaskets and custom sealing components.

• Electronic device sealing and cushioning.

• Railway, marine and outdoor equipment applications.

• Outdoor lighting fixtures and enclosure sealing.
