Ludwigshafen (Germany), 28. March 2018 – They used to be pioneers of the future, and now they’re leading innovation: the foundation for the rapid development and current success of ISOLITE was laid 40 years ago. In those days, the company had eight employees and they equipped pipelines for the aviation industry with the necessary special insulations. Now the ISOLITE Group has about 500 employees in the automotive, aviation and power generation sectors. Annual sales are rising constantly in step with the growing number of employees. Whereas the sales achieved in 1978 amounted to just 250,000 Deutschmarks, ISOLITE now has annual sales of about 75 million euros.


ISOLITE GmbH can look back on 40 years of success. Although the first team of experts for the field of high-temperature insulation was not assembled until 1978, the chemist Dr. Karl Grünzweig and the merchant Paul Hartmann laid the foundation for the establishment of the company 100 years before that. Their mission was to create ways of saving energy and improving efficiency within everyone’s reach.

At its current main site and technological location in Ludwigshafen, ISOLITE soon became an international supplier of high-temperature and high-tech insulation solutions. Under the motto “Think globally – act locally”, the Group is now to be found at ten sites in five countries. An essential part of the team, including the senior management Matthias Kroll and Christian Eck, has grown up with the company – a factor which has become rare nowadays and reveals the long-term orientation of this medium-sized German company.

Dynamic growth was the result when the first components for the aviation industry were equipped with various insulation systems in 1978 and a large-scale production order for an insulated exhaust gas recirculation pipe came from Daimler in 1995. In the 20 years that followed, orders for vehicles such as the Porsche Carrera GT and the Audi R8 enabled the expert company to further consolidate its position as a leader of innovation.


In addition to the successful global expansion it achieved by opening its first international plant in the US in 2012, the Group was proud to see the Japanese Hitachi Chemical company became a new shareholder last year. In early 2017, the materials expert acquired the majority share of the former shareholder HQ-Equita. As is usual with Japanese companies, Hitachi will keep the existing business policy with its long-term orientation in place. The combined materials expertise of both companies gives ISOLITE the opportunity to make successful growth and internationalization happen even more rapidly than before, the focus being on the European, Asian and North American markets.


“We’re well prepared for the electric cars market,” explains Matthias Kroll, CTO/CSO of ISOLITE GmbH. “The ever-increasing demands made on the automotive industry mean that manufacturers and suppliers are currently facing a lot of pressure. We see this as an opportunity to cooperate with our customers worldwide in developing trail-blazing solutions for the mobility of tomorrow.”

With the range of products it offers, ISOLITE GmbH has been doing pioneering work in the field of high-temperature insulation for several decades now. An up-to-date example of this is the purge air duct for insulating entire component groups which was specially developed for the Porsche Panamera. Thanks to its expertise in the field of battery and high-tech insulation, ISOLITE GmbH provides the solutions required today while being well prepared for the developments of tomorrow.
