TPU - Thermoplastic polyurethane

TPU (or PU) are thermoplastic elastomers that combine the elastic properties of elastomers with the mechanical properties of plastics.

The most important property of PU is its excellent wear resistance. This property make this material perfect for machined seals that fit all hydraulic or pneumatic applications.

• AU (poyester): has a very good resistance to oils despite being subject to hydrolysis.
• EU (polyether): is not subject to hydrolysis but has a lower resistance to oils.
