Your development partner with leading materials expertise

Innovative rubber and bonded rubber seals contribute significantly to the high performance and long life of modern vehicles. Car fluid systems can especially pose great challenges. Fuel and brake circuits, cooling and air-conditioning systems, and engine, gearbox, steering and chassis lubrication systems require sealing, insulation and vibration control solutions that satisfy a wide variety of demands. Daetwyler Rubber makes precision moulded rubber components to meet these requirements by continuously developing rubber materials with ever better performance characteristics.

Innovative solutions

The moulded rubber components that Daetwyler Rubber makes for cars have to withstand many stresses and strains: extreme temperature fluctuations, contact with all sorts of fluids, and a wide variety of mechanical and dynamic loads. Combining expertise, experience and creativity, Daetwyler Rubber keeps coming up with innovative rubber materials custom designed to suit all the demands of each particular application.
