About M+R Dichtungstechnik
Since 1995, M+R Dichtungstechnik GmbH, based in Seligenstadt, has been a supplier of sealing profiles and a manufacturer of extruded EPDM seals. The company produces rubber profiles from EPDM and NBR in hardnesses from 50 to 97 Shore A, with a focus on the extrusion of large cross-sections, demanding geometries and co-extrusions (hard/soft, soft rubber/foam rubber, multicolored). Its service portfolio includes design and toolmaking, corner vulcanization, rubber molded parts, sealing frames as well as custom and series production. Customers come mainly from custom facade construction, environmental engineering (solar energy), rail technology and industrial doors; in the certified sector, the automotive industry is also covered. References include the Elbphilharmonie Hamburg, for which M+R supplied the seals. The company continuously invests in material development, including compounds with silicone properties, particularly elastic and highly thermally conductive compounds.
