The LPR high pressure laminate is made with:
- A core of variable thickness obtained with kraft paper treated with phenolic thermoplastic resins.
- One or two decorative sides made with cellulose paper impregnated with thermosetting melamine resins, which give the surface resistance typical of laminates. The above are pressed for over an hour at a 100 kg/cm2 pressure and at a temperature on the paper above 130°C.The surface finish is embossed in the laminate through patterned steel press-plates.
The LPR high pressure laminates can be divided into two main families:
- Thin laminates with a sanded back, can be glued onto a variety of surfaces: particleboard, plywood, MDF, hardboard.
- Laminates with two decorative faces, thicker and self-supporting.
