High Pressure Laminates (HPL) consist of layers of cellulose fiberfiber (usually Kraft paper) impregnated in thermosetting resins and bonded through the combined action of heat (= 130°C) and high pressure (= 7Mpa).
The process takes place in multi-daylight presses and consists in the poly-condensation of the thermosetting resins, which yields a non porous, homogenous material
with strong internal cohesion (= 1,35 g/cm3).
During the pressing process, metal plates impress a texture onto the laminate surface which, depending on the function and the desired scratch and wear resistance, ranges from high glossy to deeply structured.
HPL is supplied as panels in a combination of sizes, thickness, décor and surface textures.
