Stringent testing

Karl-Josef Stühler, Head of Rheology at the LANXESS Technical Service Center in Leverkusen, prepares a rubber test strip. He was involved in developing the tear analyzer, which is used to test the tensile strength of rubber samples. This apparatus is now in use around the world.

We apply more than 400 different methods, including mechanical, dynamic mechanical and extremal tests, to evaluate our rubber products and their properties. Our testing facilities in Germany, the Netherlands, China and Canada produced around 11,000 rubber compounds in 2012, each of which was extensively tested. Our physicists and chemists are also working systematically to optimize existing tests and develop new methods.

Our customers benefit particularly from our considerable testing expertise. This year, we introduced a concept tire we developed in-house on the basis of our synthetic rubbers. This tire was one of the first to be awarded a double-A rating for fuel efficiency and wet grip in accordance with the new E.U. tire labeling regulation. Thanks to our expertise in assessing the impact of different grades of synthetic rubber on the running properties of tires, which we acquired during the development process, we will in future be able to offer materials that have been pre-evaluated in stringent tests. This represents real added value for our customers because it will enable them to shorten the time to market for new tires and strengthen their competitive position.
