Infinergy® is Empowering Movement

We are accelerating with the world's first expanded thermoplastic polyurethane (E-TPU). With Infinergy®, we help game changers and go-getters move ahead in life. We empower workers to move like athletes, children to play more safely and athletes to perform at their best.

Infinergy® provides superior energy return while delivering a lightweight, high strength alternative. Infinergy® adds next-level comfort and flexibility in a variety of applications ranging from footwear to flooring to sports equipment.

Like its base material TPU, Infinergy® is noted for having high elongation at break, high tensile strength and strong abrasion resistance. In addition, the innovative particle foam remains highly elastic and soft over a wide temperature range. It is also made out of material that has good chemical resistance.

The feature of Infinergy®’s that is particularly striking is its high resilience.

Tests of its resilience elasticity under ISO 8307 (the ball rebound test) show thatInfinergy® achieves a rebound of over 57%. This is therefore significantly higher than comparable particle foams such as expanded polypropylene (EPP) at 30%, ethylene vinyl acetate (EVA) at 37% or  expanded polyethylene (EPE) at 50%. Infinergy® maintains its excellent resilience even under a continuous load.

Measuring the rebound according to DIN 53512 (using a defined pendulum hammer), a rebound value of at least 57 to 75% is achieved. Dynamic mechanical analysis has shown that, even at extremely low temperatures of -20°C (-4°F), Infinergy® still has a low dynamic modulus, is very soft and stretchy and thus does not go stiff.

Infinergy® 32-100 U10 is processed on the usual commercial steam chest molding machines designed for a minimum steam chamber pressure of 5 bar. 

Steam pressures are typically 0.6 – 2.2bar, depending on the Infinergy grade as well as part geometry and density. Infinergy® 32-100 U10 is processed by either crack filling or pressure filling, so part densities of 200kg/m3 to about 300kg/m3 are achievable depending on the degree of packing. Infinergy can also be processed by molding technologies not using steam e.g. high frequencyand variotherm molding.

In addition, because polyurethanebinders adhere so well to Infinergy®, processing techniques such as gluingand foam sealing of the beads enables large-scale processing of Infinergy®.

Converters can process panelsmade from Infinergy® on conventional splitting machines, punches and water jet cutting machines.

Infinergy® is compliant with the RoHS directive and does not have to be labeled under dangerous goods regulations.
Information on other regulations, e. g. GADSL, will be provided on request.
Infinergy is also recyclable.
