Thermoplastic Polyurethane (TPU/AU)

Thermoplastic Polyurethane (TPU) seals are characterised by especially high efficiency. TPU O-rings have very high mechanical values including resistance to friction and tearing, very good rebound properties and high gas proof properties. Resistance to fuel, and to many other common technical oils, especially those with higher aromatics content, is excellent. Thanks to its resistance to high temperatures (up to +110 °C) and good low-temperature flexibility (down to -50 °C) and outstanding resistance to oxygen and ozone, an O-ring seal of TPU can be expected to last a long time.
