HPL 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. 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). The combination of heat and pressure creates a single, rigid laminated sheet. Thermosetting creates strong, irreversible bonds that contribute to HPL’s durability. HPL is laminated to a 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, HPL is a common choice for horizontal surfaces including flooring, countertops and desktops. 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.
