HPL is a high-pressure decorative laminate, in other words a panel consisting of layers of cellulose fibres that are impregnated with thermosetting resins and subjected to a high pressure process consisting in the simultaneous application of heat and pressure. This causes at the same time the fluidization and polycondensation of the resins, resulting in a homogeneous, non-porous material with the required surface finish. HPL is supplied as panels, available in different sizes, thicknesses and surface finishes.
