TPU-X®
Competition for Rubber Elastomers
„Wherever technological life gets tough is where our TPU-X® feels at home.“
M. Hunold
The premium material TPU-X® is deployed anywhere where the highest performance is required. The revolutionary material properties of cross-linked polyurethane (TPU-X®) are what make this new material so unique. High stresses in machine and plant construction become manageable with TPU-X®.
A moulding process patented by Hunold + Knoop has made it possible to considerably simplify and speed up the cross-linking process.

The advantages of TPU-X®
- Rubber-elastic properties
- Enormous dynamic properties
- Considerably increased life expectancy under extreme conditions
- Extremely high resilience
- Very high level of “snappiness”
- Lower abrasion
- Continuous working temperature up to +120°C
- Short-term max. temperature up to +150°C
- Excellent oscillation and vibration dampening (NVH)
- Drastically shortened process chain compared to expensive vulcanisation
- Short cycle times
- 2K material combinations with other technical plastics and metals
- Settings from approx. 45°ShA to 74°ShD
- Oil and grease-resistant
- Ozone-resistant
- Odourless
- Storage stable in contrast to rubber
Areas of application include:
- Sealing technology
- Gear wheels (substitution of POM, PA, since more flexible)
- Rollers, cylinders and spindles for paper transport
The fold test shows the enormous resilience of cross-linked TPU-X® (bottom) and non-crosslinked TPU (middle).
The Vicat softening test shows that TPU-X® (purple) softens considerably later, at about 170°C, than non-cross-linked TPU (blue).
The significantly higher life expectancy of TPU -X® component (turquoise) compared to competitor products from TPU (blue) has been demonstrated in bench tests at a customer.
