High-tech rubber for a booming market

Lanxess is continuing the legacy of synthetic rubber inventor Fritz Hofmann and today brings together globally unique experience in the field of tyre and special-purpose rubber and rubber chemicals, essential for optimising modern elastomer compounds. Among the Lanxess products are energy-saving tyre rubbers, which at the same time increase vehicle safety. The portfolio also includes rubber raw materials that protect tyres from premature pressure loss and robust and weather, chemical and ozone-resistant special-purpose rubbers for seals, hoses, v-belts, toothed belts, tank linings and others. Rubber chemicals from Lanxess make vulcanisation easier, for example, and protect rubber from premature ageing. Its products are also in many cases suitable substitutes for rubber chemicals with problematic properties. "The Russian market has enormous potential,” said Christoph Kalla, head of Marketing in Lanxess' Performance Butadiene Rubbers business unit. "The need for tyres will grow further in this global region. At the same time, resource management in Russia is a topic that is steadily increasing in importance. This makes us the perfect partner for the local rubber industry: Lanxess products help to save fuel and make winter tyres safer - and generally give tyres a longer service life.” Examples include new SSBR rubber grades that can be combined with silica filler, reducing the rolling resistance of tyres without adversely affecting abrasion and road holding, which was a major problem with many preceding generations of tyre rubbers. New neodymium-polybutadiene rubbers (Nd-BR) also help to reduce rolling resistance thanks to a particularly regular molecular structure imparted to them by the company's technology. Butyl rubber from Lanxess reportedly keeps the air pressure in tyres constant for longer - this also has a positive effect on fuel consumption. The HNBR elastomer Therban helps to increase the service life of toothed belts used under the hood in the ever hotter conditions found near the engine, while oil and chemical-resistant rubber grades are proving their worth, for example, in hoses that convey aggressive media which would cause conventional rubber to swell or become brittle. Seals made out of EPDM rubber Buna EP withstand UV light and ozone longer than those made of natural rubber thanks to their chemical structure. Antioxidants, vulcanisation accelerators, plasticisers and antiozonants from Lanxess and its subsidiary Rhein Chemie Rheinau GmbH based in Mannheim, Germany, help high-tech rubbers achieve top performance, while many speciality chemicals in Rhein Chemie's Rhenogran and Rhenocure ranges offer toxicologically safe alternatives to problematic speciality chemicals, impressing as vulcanisation accelerators for acrylic and chloroprene rubber, among other applications. According to Frank Lueckgen from Rhein Chemie's Rubber Division: "We consider Russia as a growth market. With our broad product portfolio and our innovative high quality products we are perfectly prepared to participate in that growth.” "Lanxess not only offers solutions in the form of advanced rubber raw materials but also provides experts who work side by side with our customers and help them get the best out of their products,” added Kalla. "At the same time, our customers can benefit from our global network. I find it fascinating to discover time and again how similar the needs of our global customers are. Here, we offer a window that offers expanding companies important perspectives,” added Kalla. He continued: "We are also interested in further applications in which at the moment other materials are used. We would like to learn more in this context and help to increase added value through our rubber expertise - for example in the field of conveyor belts for ore transport or in the growing market for consumer goods.”
