High Pressure Laminates are sheets consisting of layers of cellulose fibrous material (normally paper) impregnated with thermosetting resins and bonded together in a high pressure process. The process, defined as a simultaneous application of heat (≥ 120 °C) and high specific pressure(≥ 7 MPa), provides flowing and subsequent curing of the thermosetting resins to obtain a homogenous non-porous material (> 1,35 g/cm³) with the required surface finish.
