Safety hose resistant to chemicals.

摘要

The hose (1) has a walling (2) of polymer, partic. elastomers, and contains at least to concentrically arranged reinforcement inlays (3,4) comprising fibres or threads. The radial outer reinforcement inlay has a greater chemical resistance to media conveyed through the hose than the radial inner reinforcement inlay. The polymer outer walling layer (2.2) surrounding the radial outer reinforcement inlay (4) is finely perforated. The internal width of the perforation channels (5) is less than 0.5 mm. The perforations are formed by closed, elastically widenable channels (5) and their density amounts to 0.5 to 5 channels per cm2.
