The TPU diaphragms.

Polyurethane reportedly makes it possible to adapt sealing materials to meet exact user requirements, due to its molecular blueprint and its controllable chemical synthesis.

The TPU diaphragm material has more tear propagation resistance than conventional elastomers and high tensile strength and elasticity. They also have improved tear propagation properties and flexural fatigue strength. When bonded with PTFE films they can be used in conjunction with very aggressive media, and are resistance to ozone and oxidizing agents.
The shape and geometry of the diaphragm, as well as the fabric inserts, PTFE protective film, inserts, and overall composite structure can be adapted to meet the relevant set of requirements in a given application. The diaphragms are suitable for vacuum pumps, double diaphragm pumps, or diaphragm metering pumps, pneumatic systems, fittings, air conditioning and heating technology, sanitary systems and architectural engineering.
They can also be used in existing pump and component ranges.
