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:
