| HPL (High Pressure Laminate) |
| The laminate is made up of a series of
Kraft paper layers impregnated with a special phenolic resin. External decorative paper
sheets are impregnated in melaminic resin following a specific program of decoration and
sizes. The basic parts are then impregnated in thermosetting resins, appropriately treated, that give the product its fundamental physical-mechanical features. It subsequently undergoes a combined action of pressure (9 MPa) under heat (150°C), in hydraulic presses that provokes an irreversible chemical-physical transformation caused by the polycondensation of the resins used. |
