puren gmbh is located in Überlingen at Lake Constance and has been in existance for over 46 years.  This makes the mid-size, internationally operating group of companies, with approximately 300 employees headed by Dr. Andreas Huther as managing director, a pioneer in the industry of polyurethane (PUR/PIR) rigid foam technology.

Innovation has been a passion of the founder and acting partner of the company, Hans Bommer, right from the start of business:  In 1968, polyurethane rigid foam was nearly unknown in Germany.  By accident, Hans Bommer got acquainted with this multifunctional, high-performance insulating material and quickly visualized its multitude of possible applications.  Having made investigating trips to find out about its technical properties and ways of manufacture, he started a kind of “shop”, and produced his first PUR rigid foam slabstock with only one employee. His entrepreneurial spirit quickly showed results and over the years the 2-man operation grew into the actual group of companies, today operating several production sites and sales offices domestically as well as a Joint-Venture in China since 1996.

Always, Hans Bommer placed an important emphasis on issues such as protecting the environment, saving on energy and resources. Already at the beginning of the seventies, when nobody was addressing topics such as the protection of the climate, water and nature, reducing the emission of CO2 or the greenhouse effect, Hans Bommer was far ahead of the trend by recycling production remnants and as a result developed the functional material purenit® together with efficient oil and chemical binding agents for soil and water.  To-date, this is still reflected in our company philosophy: "Generating/saving energy and reducing the emission of hazardous materials and substances with insulation, heating and environmental technologies by developing innovative products."
