The materials that form part of this group have as a fundamental characteristic a low remaining deformation under conditions of constant deformation and in contact with fluids. We stock a wide range of materials for the sealing applications of mineral and synthetic hydraulic fluids, water, steam and chemically aggressive fluids, working temperatures between -55ºC and 200ºC, FDA regulations, CE 1935/2004, KTW, 3A and USP class VI.
