Comparison of the rebound of different foams [Molding density: 30 kg/m3 and 265 kg/m3 (Infinergy®)]

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 that Infinergy® 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 frequency and 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.

Broader processing spectrum accessible by novel surface tuning of foam particles

BASF will soon introduce particle foams with a polymeric surface functionalization that provides access to a variety of molding processes, such as hot pressing, RF welding, and other molding technologies. In a novel process, the particle foams are provided with a uniform polymeric surface functionalization. The treated foam particles are storable and can be fused into molded parts in a much more energy-efficient and material-friendly manner. The novel surface-tuning can be applied to almost all material classes, such as expanded particle foams made of thermoplastic polymers, thermoplastic polyurethanes and thermoplastic elastomers. With the surface functionalization it becomes possible to combine different kind of materials as well as to embed inserts, and, therefore obtain a tailor-made design of molded parts in one processing step.

Das Besondere an den Materialien der BASF sind zum einen ihre herrausragenden Eigenschaften und zum anderen die Produktideen, die sie ermöglichen. Diese werden in der sogenannten „Wunderkammer“ präsentiert, einem Trichter, dessen Wände die Augen abschirmen und den Betrachter so jede räumliche Orientierung verlieren lassen. Die perspektivische Verzerrung lässt sowohl Objekte als auch Besucher in einer verblüffenden Collage verschmelzen. Ein Spiel mit der Wahrnehmung – genauso charmant und analog, wie es 1865, im Entstehungsjahr der BASF, noch gang und gäbe war. What makes BASF materials special is both their excellent properties and the product ideas they enable. These products are presented in the so-called “Wunderkammer”, or “cabinet of wonders” – a funnel, whose walls block off the peripheral view to suspend spatial orientation. The perspective distortion merges objects and visitors moving amongst them into an astonishing collage. Playing with perception – in just the same charming, analogue way as was so popular in 1865, the year in which BASF was founded.
