In addition, tailor-made materials for a wide range of applications can be produced by adapting the starting components and adding various additives.
Polyurethanes can be used as thermoplastic polyurethanes (TPU) in injection molding, but are traditionally processed in reaction moulding machines. These machines mix the starting materials in a high-pressure or low-pressure process and then allow direct injection into a mould or open discharge. Special versions of the so-called mixing head and associated nozzles also allow the spraying of polyurethanes.
