Die-cut from sponge or foam rubber sheets, these gaskets leverage a unique cellular structure to provide excellent compressibility, shock absorption, and effective sealing on uneven surfaces. Ideal for thermal and acoustic insulation, they are commonly produced in materials like EPDM, Neoprene, Silicone, and Nitrile Sponge for applications including enclosure gaskets (electrical/HVAC), vibration damping pads, and lightweight door seals.
