EPDM sponge rubber cords are flexible, compressible sealing components designed for effective sealing, cushioning, and insulation in applications exposed to outdoor weather, heat, moisture, and environmental aging. Manufactured from closed-cell EPDM sponge rubber, these cords provide excellent resilience and recovery under compression, making them ideal for static sealing applications where low clamping force and surface irregularities must be accommodated. EPDM sponge rubber cords offer outstanding resistance to UV radiation, ozone, rain, and temperature fluctuations, ensuring long service life in both indoor and outdoor conditions. Their closed-cell structure helps prevent water absorption and air leakage, providing reliable sealing performance in doors, windows, enclosures, and panels. EPDM sponge rubber cords are widely used in HVAC systems, electrical enclosures, automotive body sealing, bus and rail coach interiors, building construction, glazing systems, and general industrial applications. They are available in round and custom cross-sections and can be supplied in continuous lengths or cut sizes, with easy fabrication into rings or frames when required. Typical service temperature ranges from approximately –40 °C to +120 °C, depending on compound formulation. Due to their excellent weather resistance, flexibility, and compression sealing efficiency, EPDM sponge rubber cords are a dependable solution for long-term sealing, insulation, and vibration-damping applications where oil resistance is not the primary requirement.
