    High Pressure Laminates (HPL) for Decorative Surfaces

    View:39105/30/2019  

    High Pressure Laminate or HPL, is the direct descendent of the original plastic laminate. It is considered to be one of the most durable decorative surface materials and is available with special performance properties including chemical, fire and wear resistance. Special grades of HPL can be postformed around curved edges by application of heat and restraint.

    HPL is produced by saturating multiple layers of kraft paper with phenolic resin. A layer of printed décor paper is placed on top of the kraft paper before pressing. The resulting sandwich is fused together under heat and pressure (more than 1,000 PSI). Because phenolic and melamine resins are thermoset plastics, the curing process transforms the resin into plastic by a cross linking process that converts the paper sheets into a single, rigid laminated sheet. Thermosetting creates strong, irreversible bonds that contribute to its durability.

    High pressure laminate is laminated to a composite panel utilizing a variety of adhesives. Particleboard or MDF are the preferred substrate because they provide a stable, durable, consistent and economical foundation. Due to its durability, high pressure laminates are a common choice for horizontal surfaces including flooring, countertops and desktops.

    High pressure laminate (HPL) countertops aren't just for kitchens; they can stand up to the rigorous demands of science labs and classrooms. It also performs well in horizontal and vertical applications for high traffic settings such as hospitality, office furniture, healthcare, retail casework, commercial interiors and educational facilities.


    There are many types or grades of high pressure laminates (HPL) engineered for specific performance requirements:

    GENERAL PURPOSE

    Most widely used HPL and suitable for horizontal and vertical surface applications. Typical thickness range from 0.028” to 0.048” (0.71 to 1.22 mm).

    POSTFORMING

    Can be formed around curved edges by application of heat and restraint. Maximum thickness is approximately 0.038” (0.97 mm) and can normally be formed to radii as small as 3/8” (9.5 mm).

    BACKER

    HPL produced without a decorative face. Available as standard (most common; slightly thinner than decorative HPL) or regrind (reclaimed HPL with decorative sheet sanded off).

    SPECIAL PRODUCTS

    Special purpose high pressure laminates include cabinet liners, high-wear, fire-rated, electrostatic dissipative and chemical resistant laminates.
