HPL is typically constructed of several layers of high quality kraft paper, a layer of decor paper with solid colour or printed design, and topped with a protective wear layer that can also carry printed design accents or brushed metal or other inclusions.
The kraft layers are generally impreganted with thermosetting phenolic resins; the decorative and wear layers are saturated with thermosetting melamine resins. Because HPL sheetss are pressed individually, many different designs and colours can be offered. Textured press plates may be used to control gloss levels, or impact textures that mimic stone or natural wood surface designs.
Normally specified for high-use applications like counters, desktops and kitchen panels, LITESPAL is laminated over a variety of substrates and thicknesses but usually on MDF. HPL is easily laminated and is available in single and double face options.
