Closed-cell sponge rubber made from Nitrile Butadiene Rubber (NBR) and Polyvinyl Chloride (PVC) blend, manufactured by continuous extrusion and foaming process. Offers an optimal balance of oil resistance, thermal insulation, and mechanical flexibility for industrial sealing and insulation applications

Unlike ordinary rubber foams that degrade when exposed to oil or harsh chemicals, our NBR/PVC blend is engineered to last. It resists fuels, greases, and industrial fluids while delivering superior thermal insulation and vibration dampening – all in a lightweight, flexible sheet that's easy to work with.

What makes it your best choice？

• Oil doesn't kill it. NBR content gives it exceptional resistance to petroleum-based fluids – something EPDM or natural rubber simply can't match.

• It saves energy. With thermal conductivity as low as 0.038 W/mK, it keeps cold in and heat out, reducing energy bills in HVAC and refrigeration systems.

• Water stays out. The closed-cell structure blocks moisture penetration, preventing corrosion and mold growth behind the insulation.

• Noise disappears. Absorbs vibration and dampens sound, creating quieter working environments.

• Built for extremes. Performs reliably from -40°C to +110°C – cold storage to engine compartments.
