Abstract (en)
[origin: WO2021073804A1] The invention relates to a hose, which comprises at least the following layers in the sequence given: an innermost layer (A4), which is made up of thermoplastic material or thermoplastic elastomer material; an inner layer (A5), which is applied to the innermost layer (A4) and is made up of elastomer material; at least one reinforcing-element layer (B, B1, B2), wherein the reinforcing element is arranged at an angle less than the neutral angle of 54.7°, and possibly an outer layer (C), which is made up of polymer material. The hose is suitable in particular as a pressure-carrier hose for refrigerant lines, in particular for CO2, for use as a pressure carrier of corrugated pipes.
