Linoleum consists entirely of organic and mineral raw materials, of which over 80% are renewable, with no significant changes having been made to these ingredients since the invention of the product in the 19th century. The elements making up linoleum:
Linseed oil, wood flour, limestone, jute and resin are the main constituents of the linoleum manufactured today. In an oxidation process, the linseed oil is converted to linoxyn, a viscoplastic material that, with the addition of resins and drying agents, forms an elastic mass known as linoleum cement. This is drawn out into a rope, cut into sections and stored until it is time for further processing.
Linseed oil, which is obtained from the seeds of the flax plant. The main countries supplying this oil are Canada and Argentina, although linseed is also cultivated in Europe, predominantly in France, the United Kingdom and the Eastern states of Germany.
Resins are the second important component of the binding agent alongside the linseed oil. In general, natural resins from plantation trees are used.
Wood flour and cork flour
Wood flour, from Scandinavia or Germany, and cork flour, which is obtained from the bark of the cork oak and from cork waste, are used as fillers.
Ground limestone (chalk) is found as a filler in many elastic floor coverings.
Linoleum dust is produced by shredding, crushing and grinding the production waste and is re-added to the basic mass in measured quantities.
Jute fabric forms the backing material for the linoleum. The jute mainly originates from cultivated plants from Bangladesh and India.
Colour pigments are of natural origin or nature-identical and do not contain lead, cadmium or chromium these days.
Due to the natural raw materials and their unique colourations, all pigments are added individually by hand from the colour mixer during the manufacturing process.
