Hose, especially pneumatic hose of thermoplastic polyurethane, is formed from polyurethane source material and subsequently added di-isocyanate

摘要

The hose (1) is especially a pneumatic hose of thermoplastic polyurethane, whereby the thermoplastic polyurethane is formed from a polyurethane source material and subsequently added di-isocyanate. A hose then emerges extruded from the molten polyurethane. The subsequently added di-isocyanate with regard to the mass of the polyurethane source material is added to the polyurethane in a volume of preferably 0.5 to 3.5 weight percentage. The di-isocyanate is at least one substance of the group diphenylmethane -4,4'- di-isocyanate, toluylene di-isocyanate.
