Design of Diaphragm Materials

Diaphragm materials are our engineering basis for the manufacturing of diaphragms. Diaphragms are designed with at least two components: an elastomer and a textile reinforcement. Together with our customers we select the best material to meet the requirements of the final application.

Technical specifications

  • Temperature resistant from -40°C to +250°C
  • Permeation resistant
  • Resistant to commercially available fluids and gases
  • Tear-resistant from 10 to 1,000 N/cm
  • Elongation from 2 to 30%

Features & benefits

  • High flexibility and low hysteresis
  • Constant effective area
  • Short reaction time in the event of pressure change
  • Extremely resistant to pressure
  • Long service life
  • No frictional loss when starting or when in operation
  • No maintenance or lubrication


We can meet different requirements from various industries with a wide range of materials, processes and design options. From generating of energy to transporting and consumption, our diaphragms are used in various assemblies and inherit the function of pumping, controlling, regulating and separating.


Diaphragms - flat and shaped - are used in fuel supplying systems

  • controlling fuel flow through
  • damping vibration and pressure peaks
  • separating and transporting liquids and gases

Other applications include brakes, air condition, EGR and sound - engineering.

Supply Engineering

In gas, water and air condition engineering (supply engineering) our diaphragm and elastomer coated fabrics perform key functions that ensure the comfort and well being of people. They contribute to the production of heat and hot water in private households as well as industrial settings. From generating energy to transporting and consumption, our diaphragms are used in various assemblies, such as actuators, pumps, pressure regulators and gas meters.

Medical Equipment

Measuring and controlling highly sensitive procedures: thin but flexible diaphragms are ideal for this function in many applications. In medical equipment, e.g. in infusion pumps, the inclusion of protective diaphragms makes a contribution to protecting and saving life.

Aviation and Aerospace Industry

We also supply the aviation and aerospace industries with diaphragm materials. With our well organized quality management, we are approaching our target of zero - defect quality. This means extra reliability for our customers and for us.
