When Lonza decided to divest itself of this new product development, it was Mr. Bauer - at that time the leading project engineer on this new tubular honeycomb technology - who purchased the technology and set up Tubus Bauer GmbH in 1972 in Wallbach, Germany.

The first market for Tubus Core applications was the refrigeration industry, since the laminarization of airflow is very critical to manufacturing an economically refrigerated showcase. It did not take long for Tubus Bauer to become the sole source for this industry and, within a few years, Tubus Core was used by all major manufacturers of refrigeration display cases in Europe. This new technology spread - basically only through word-of-mouth - and established itself in the European market of vertical refrigeration display cases.

In 1991, the Bauer family decided to look for a new stakeholder to bring Tubus Bauer to the next level. During the next two years, analyzing and developing new products became the main focus of the company's new management. It resulted in the creation of a new co-extrusion technology in 1994, which today still is the key technology under the patent of Tubus Bauer.

Since its beginnings as a single-market and single-product company in 1991, Tubus Bauer has become a multi-product and multi-market company. Its tubular honeycomb meets the stringent requirements of many different markets, such as aerospace, automotive, laminar airflow, architecture, military and many others.
