Kron International started under the name Stockholms Borstbinderi AB. Between the five companies this is the company that has hold on to the original product the most. The company still produces various brushes although it has added the assortment. The old companies Perstorp AB and Alfa Laval have changed almost their entire original production. The development of productions has gone from charcoal, acetic acid and plastic products to a high-tech chemical industry with two main areas, specialty chemical and materials technology. Alfa Laval started with the milk-skimming separator and has now four main areas; food supplies, life science, energy and environment conservation. Backer AB started with element and has today three areas; element, stoves and heating. Furninova started with furniture and has not changed the product area.

   When it comes to the degree of high-tech we consider Alfa Laval, Perstorp AB and Backer AB to some extent to be involved with more or less high-tech products, while Kron International and Furninova produce less technological products. We think that the degree of high-tech has been an underlying factor for expansion and internationalisation regarding Alfa Laval, Perstorp AB and Backer. The studied companies show great differences in the degree of internationalisation. Alfa Laval has the highest degree with 92 %, followed by Perstorp AB with 90 % while Backer AB and Furninova is found in between, with 65 and 55 %. The lowest degree has Kron International with 20 %. A conclusion to be drawn from this is that there seems to be a correlation between the degree of high-tech and the degree of internationalisation between the studied companies. It seems as if the companies with a high degree of high-tech also have a high degree of internationalisation. Another conclusion is that companies with a high degree of internationalisation exist in industries where the degree of internationalisation of the market also is high. Kron International has a low degree of internationalisation and acts in a market with low internationalisation.
