EHPL - MATERIAL
EHPL – Exterior High Pressure Laminate comes as flat sheets made from paper fibre and wood pulp pressed together with phenolic resin glue at high pressure and high temperature. The surface is made from pigmented resin tempered using electron beams. The smooth, robust surface is easy to clean and allows for easy removal of graffiti. The sandwich-construction and the combination of materials combine to form a highly robust material, suited to many years of outdoor use.
The EHPL used for outdoor furnishing is typically 8-12 mm thick.
Unlike wood, EHPL does not become moist, nor does it feel hot/cold like steel and concrete.
EHPL fades minimally when exposed to sunlight (UV level 7-8 out of 10) and is not impacted by wind and weather. It is maintenance-free and easy to clean.
Cleaning can be carried out using ordinary cleaning agents and/or high-pressure cleaners.
At the end of its lifecycle EHPL-objects can be cut up and used as building filler.
EHPL cannot be set alight by cigarettes, matches or lighters, but only using gas burners.
Application temperatures range from -20 to 80 degrees Celsius.
EHPL - PROCESS
This is a fairly complex production process featuring presses (high pressure) working at high temperatures and a subsequent surface processing. The sheets can then be cut, bent, glued or laser-cut. Logos or names may be milled into the surface.
Only a few European companies master the production of HPL-sheeting and only one or 2 manage to postform the exterior sheets

Out-sider has several product families made from HPL including many variations of Plateau, EHPL Picnic, SuperFine and SuperFly.
