​Open cell rubber foam is elastic porous rubber sponge with connected open cells. It has superior heat insulation, sound deadening and cushioning properties. Fire retardant grade options support commercial HVAC and refrigeration pipeline insulation, perfectly matching copper tubing, thermal wrap and insulation accessories to stop condensation and energy loss.

Open cell rubber foam is a soft, elastic porous sponge material with interconnected internal pores. Different from closed-cell foam, its open-cell structure delivers excellent sound absorption while maintaining reliable thermal insulation performance.

Manufactured from high-quality rubber compound, this foam features low thermal conductivity, outstanding flexibility, and strong resistance to moisture, mold and aging. Custom fire retardant, low-smoke formulations are available to meet international construction fire safety standards, ideal for commercial and residential HVAC projects.

Our product range covers foam rolls, flat sheets, pre-formed insulation tubes and self-adhesive foam tapes. It is widely applied as pipe wrap for ACR copper tubes, refrigeration pipelines and central air-conditioning systems. It effectively eliminates surface condensation on metal pipes, reduces energy loss and absorbs pipeline operation noise. We also support customized thickness, density and adhesive backing to match all kinds of insulation accessories.
