Heat Insulation Sponge
Our Heat Insulation Sponge works by a simple principle. The sponge has many small holes. Inside the holes, there is still air. Still air does not move. So heat does not pass through easily. This slows heat transfer. We make three types. First, PU insulation sponge. Light and soft. Easy to cut and stick. Good for appliances and building insulation.

Keeps Heat Where It Belongs
Our Heat Insulation Sponge works by a simple principle. The sponge has many small holes. Inside the holes, there is still air. Still air does not move. So heat does not pass through easily. This slows heat transfer. We make three types. First, PU insulation sponge. Light and soft. Easy to cut and stick. Good for appliances and building insulation. Second, rubber-based insulation sponge. Uses PE, EVA, or rubber. Closed cell. Elastic and bends well. Water and moisture resistant. Good for pipes and air conditioners. Third, ceramic composite sponge. Handles higher temperatures. Good for battery insulation and industrial equipment. We are Jiangsu Palatus. We offer free samples.

Used in Buildings, Appliances, and Cars
Our Heat Insulation Sponge is used in many places. Building and HVAC: wall and roof insulation, air duct insulation. Industry: equipment insulation, oven insulation, precision instrument temperature control. Transportation: car engine insulation, EV battery thermal management, train interiors. Others: cold chain logistics, sports equipment, special packaging. This sponge has low thermal conductivity. The lower the number, the better the insulation. We can make many densities. Flame retardant levels can meet B1, B2, or UL standards.
Full Customization and Full Production Chain
You can customize our Heat Insulation Sponge in many ways. Size, shape, density, and flame retardant level. We can also add adhesive backing. Do you need a small sample? Yes. Do you need large stable supply? Yes. We have a full production chain. From raw material modification to foaming to finishing, we do it all. Contact us for samples and technical data.
