The origin of HPL The history of HPL

In 1907 the first patent was granted to the Belgian chemist Leo H. Baekeland for a product type with

the commercial name “Bakelite”: A mixture of wood flour or fibres with phenol resins could be

pressed in metal forms and simultaneously cured by heat.

In flat form produced as sheet material by impregnating paper with phenol formaldehyde resin and

cured between steel plates, it became a replacement for mica as carrier for electrical components in

consumer products of the 1920’s such as radios and switchboards.

First melamine formaldehyde reactions were explored in 1906 and made commercially during the

1930’s by different companies.

The development of decorative papers with a high absorption for melamine formaldehyde resins was

the basic step to a decorative laminate during the 1940’s.

A combination of phenol resin impregnated Kraft paper with a lightfast and coloured melamine resin

impregnated decorative paper on top pressed together and cured under heat had an rapid devel

opment during the 1950’s:

Some key-developments of HPL for special market segments are:


 Heat resistance or cigarette-proof quality with an inlay of aluminium foil for heat transfer.

 Self supporting HPL or compact HPL in thickness between 2 and 30 mm.

 Postforming HPL


 Fire retardant HPL for transport and wall cladding.

 HPL with highly textured surfaces.

 Electrostatic dissipative laminates for antistatic applications.


 Wear resistant laminates for counter tops and domestic flooring systems.

 Outdoor HPL compact laminates with weather-resistant surface protection.

 HPL with metal surfaces.

 HPL with wood veneer surfaces.

 HPL with chemical resistant surfaces.


 Continuously pressed high pressure laminates.

 Compact laminates with alternative core materials.
