HPL honeycomb panel is a combination of HPL decorative sheet and pp honeycomb core.
HPL means High-Pressure Laminate, it a decorative laminate of furniture surface materials or wall paneling.
HPL honeycomb Panel has many advantages like:
1) Colorful surface;
2) Lightweight;
3)Strong structure;
4)No water or moisture absorption.
Base on the test, For a 20mm thick panel, the area weight is about 5 kgs/m2, this is only 1/3-1/2 of the area weight of the same thickness of plywood.
This special composite can be widely used in RV, lightweight furniture, outdoor furniture, and other decorative constructions.
HPL honeycomb panel is a commercially supplied product.
Background knowledge of HPL:
High-pressure laminate (HPL)[edit]
According to McGraw-Hill Dictionary of Architecture & Construction, high-pressure laminates consist of laminates “molded and cured at pressures not lower than 1,000 psi (70 kg/cm2) and more commonly in the range of 1,200 to 2,000 psi (80 to 140 kg/cm2).”[1]
HPL is made of resin impregnated cellulose layers, which are consolidated under heat and high pressure. The various layers are described below:
Trade names include Formica, Arborite, and Micarta.
After the papers are impregnated with the resins, the three layers of paper/resin are placed into a press that simultaneously applies heat (120 °C) and pressure (5 MPa). The pressing operation allows the thermoset resins to flow into the paper, then subsequently cures into a consolidated sheet with a density greater than 1.35 g/cm3 (84 lb/cu ft). During the press cycle, the decorative surface can also be cured while in contact with a textured surface to create one of many different surface finishes.
HPL consists of more than 60 to 70% paper, with the remaining 30 to 40% a combination of phenol-formaldehyde resin for the core layers and melamine-formaldehyde resin for the surface layer. Both resins belong to a class of thermosetting resins that crosslink during the press cycle creating irreversible chemical bonds that produce a nonreactive, stable material with characteristics different and superior to those of the component parts.
HPL can be produced using both continuous and discontinuous (batch) manufacturing processes. HPL is supplied in sheet form in a variety of sizes, thicknesses, and surface finishes.
