The invention relates to a hose having at least the following sheet layers in the following order: an innermost layer (A4), which is based on a thermoplastic material or a thermoplastic elastomer material; an inner layer (A5) applied to the innermost layer (A4) and based on an elastomeric material; the reinforcing elements are arranged at an angle of a neutral angle of less than 54.7 DEG, and possibly an outer layer (C) based on a polymer material. The hose is particularly suitable as a pressure hose for refrigerant lines, in particular for CO2, as a pressure hose for bellows.

    本发明涉及一种软管,该软管按以下顺序至少具有以下片层:最内层(A4),该最内层是基于热塑性材料或热塑性弹性体材料;内部层(A5),该内部层施加到该最内层(A4)并且是基于弹性体材料;至少一个加强元件片层(B,B1,B2),其中,该加强元件以小于54.7°的中性角的角度布置,以及可能的外部层(C),该可能的外部层是基于聚合物材料。该软管作为特别是用于CO2的制冷剂管路的载压软管特别适合用作波纹管的载压件。
