Infinergy

Like its starting material TPU, InfinergyTM is noted for having high elongation at break, tensile strength and abrasion resistance as well as good chemical resistance. In addition, the innovative particle foam remains highly elastic and soft over a wide temperature range.

The feature of InfinergyTM that is particularly striking is its high resilience. Tests of the resilience elasticity under ISO 8307 (the ball rebound test) and under DIN 53512 (using a defined pendulum hammer) show that InfinergyTM achieves a rebound of over 55 %. 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%. InfinergyTM does not lose its excellent resilience even under a continu- ous load.

Dynamic mechanical analysis has shown that, even at extremely low temperatures of -20°C (-4°F), InfinergyTM still has a low dynamic modulus, is very soft and stretchy and thus does not go stiff.
