TPU (Thermoplastic Polyurethane) is a polyurethane-based thermoplastic elastomer.

If you are looking for a very durable, oil-resistant material, TPU is a good option.

TPU is a very frequently used material in hydraulics and pneumatics applications. This is not only because of its high resistance to substances including mineral oils and fats, but also because of its excellent mechanical properties.

The tensile properties of TPU in particular are very well suited for use under high pressure. Its excellent durability has made TPU the standard in dynamic and semi-dynamic seals.

TPU offers clear advantages over thermoset elastomers as TPU can be processed cost-efficiently through injection moulding.

TPU is available from around 60 Shore A – which means not very soft varieties.

Typical properties of TPUs are:

  • Temperature reach: -60°C to +110°C
  • Hardness: 60 Shore A – 80 Shore D
  • Oil resistance: excellent
  • Acid resistance: moderate
  • Base resistance: mediocre
  • Deterioration (ozone) resistance: excellent

TPU materials are available in very many varieties and have different specific properties. Contact our material specialists to help with the right choice of materials for your project.
