How HPL Sheets are made?

The normal composition of HPL sheets is 60–70% paper and 30–40% thermosetting resins. Overlay paper, ornamental paper, and kraft paper make up their three layers. The ornamental paper adds visual appeal through design, the overlay paper helps to improve abrasion and scratch resistance, and the kraft paper serves as a core material to regulate the product’s thickness.
Multiple layers of kraft paper are saturated with phenolic resin to create it. Before pressing, kraft paper is covered with a layer of printed decorative paper. Under the influence of heat and pressure, the resultant sandwich is sealed (more than 1,000 PSI). Due to the fact that phenolic and melamine resins are thermoset polymers, during the curing process, a cross-linking reaction turns the paper sheets into a single, hard sheet, converting the resin into plastic. It is durable because of the strong, irreversible bonds produced by thermosetting.
A composite panel is bonded to a high-pressure laminate using a variety of adhesives. Because they offer a solid, resilient, reliable, and affordable base, particleboard or MDF are the recommended substrates. These are a popular option for horizontal surfaces including floors, worktops, and desktops due to their endurance.
