Co-extrusion profiles made from EPDM and sponge rubber are advanced sealing solutions manufactured by combining solid (dense) EPDM rubber with cellular sponge EPDM through a single extrusion process. This integrated construction provides the profile with the benefits of both materials: the durability, weather resistance, and structural stability of dense EPDM, along with the flexibility, compressibility, and effective sealing performance of sponge rubber. The result is a versatile sealing profile designed to provide reliable protection against dust, moisture, air leakage, vibration, and environmental exposure.
