Our square EPDM sponge foam sealing strip is a high-performance closed-cell rubber sealing solution engineered for long-lasting gap sealing, insulation and protection. Made of premium pure EPDM sponge foam material, this square foam seal strip features excellent compression resilience, zero water absorption, outstanding weather resistance and stable performance in extreme environments, far superior to ordinary PVC and neoprene foam seals.
Designed with a standard square profile, this EPDM sponge sealing strip fits various irregular and regular gaps perfectly, realizing tight airtight, waterproof, dustproof, soundproof and shockproof sealing effects. The closed-cell foam structure effectively blocks outside dust, rainwater, wind and noise, while delivering excellent thermal insulation and vibration damping functions, avoiding heat loss and equipment vibration damage.
Featuring a wide temperature tolerance range of-50℃ to +150℃, this square EPDM foam strip resists UV rays, ozone aging, chemical corrosion and compression deformation, ensuring stable service performance for years in outdoor and high-frequency use scenarios. It will not harden, crack or deform after long-term extrusion, maintaining consistent sealing performance all year round.
Available with optional self-adhesive backing, the EPDM sponge foam seal strip enables tool-free, quick and firm installation on any smooth surfaces including metal, wood, plastic and glass. No professional skills or extra glue are required, greatly saving installation time and cost. Multiple customizable sizes (3mm/5mm/10mm thickness, 5-50mm width) are provided to meet diverse residential, commercial and industrial sealing needs.
Versatile in application, our square EPDM sponge sealing strips are widely used for door and window gap sealing, cabinet and refrigerator sealing, automotive interior and exterior gap filling, mechanical equipment dustproof sealing, construction curtain wall gap insulation, electrical appliance shock absorption and other scenarios. Eco-friendly, non-toxic and wear-resistant, these industrial-grade foam seal strips are ideal for both indoor and outdoor long-term use.
