GUFERO sponge extruded cords are cords made of light (microporous) rubber. The diameter of the sponge extruded cord is expressed by the cord diameter in mm. The extruded extruded cords are soft, flexible and elastic if required and have a relatively low weight even with large diameters. The sponge extruded cords are designed for operating temperatures from -30 °C to +80 °C. GUFERO sponge extruded cords are very reliable in applications where it is not possible to use extruded cords made of compact rubber. The offered profiles are supplied in original packaging. Smaller quantities (by the meter) are available from our warehouse on request.
