Specification of PVC Sponge Foam

What Is Closed Cell PVC Foam?

Polyvinyl Chloride PVC foam is a closed cell sponge foam material designed to provide an economical solution for sealing light, air, moisture and dust. By adjusting density, hardness, resilience and surface treatment, PVC foam can deliver different levels of sealing, cushioning, compression recovery and durability for industrial applications.

For 1mm thickness, the material is especially suitable for thin foam gasket, foam tape, surface protection pad, electronic cushioning, door and window sealing, water tank sealing, HVAC sealing and vehicle body vibration damping. Topsun can convert PVC foam into sheets, rolls, strips and precision die-cut parts according to customer requirements.

Applications of 1mm Thick PVC Sponge Foam

• Door and window sealing strips.

• Truck, cab and vehicle body seals.

• HVAC sealing and air leakage control.

• Appliance sealing and cushioning.

• Die-cut foam gaskets and pads.

• Electronic device sealing and shock absorption.

• Railway and marine foam sealing applications.

• Outdoor lighting fixture sealing and protection.

Can Topsun supply 1mm PVC foam with adhesive backing?

Yes. Topsun can laminate pressure-sensitive adhesive and release liner on PVC foam to produce self-adhesive foam tape, foam strips and custom die-cut adhesive foam parts for easy installation.

Is closed cell PVC foam waterproof?

Closed cell PVC foam has good water resistance because its cell structure helps reduce water absorption. It is suitable for sealing and moisture protection, but the final waterproof effect also depends on compression ratio, installation method, adhesive type and the working environment.

Can the density and hardness of PVC sponge foam be customized?

Yes. PVC sponge foam can be customized by density, hardness, resilience, thickness, color, adhesive backing and flame retardant grade. Customers can send drawings, samples or application requirements for material recommendation.

What formats can 1mm closed cell PVC foam be supplied in?

It can be supplied in sheets, rolls, strips, tapes, pads, gaskets and precision die-cut parts. Topsun can also provide lamination, cutting, die cutting, laser cutting, engraving and printing according to your production needs.

How do I choose the right PVC foam for my sealing application?

To choose the right PVC foam, confirm the required thickness, compression space, sealing pressure, working temperature, indoor or outdoor use, adhesive requirement, flame retardant requirement and part size. For 1mm foam, it is important to check whether the gap is small enough to create stable compression after installation.
