Abstract
(EN)
A hose which comprises an inner layer (1) and an outer layer (2) surrounding the periphery of the inner layer, wherein the inner layer is made of a thermoplastic olefin elastomer comprising polypropylene (PP) and an acrylonitrile/butadiene rubber (NBR), and the outer layer is made of a thermoplastic olefin elastomer comprising polypropylene (PP) and an ethylene/propylene/diene rubber (EPDM). The elastomer constituting the inner layer preferably contains 1 to 5 wt.% stabilizer comprising an amine compound or a mixture of a thioether compound and a hindered phenol compound. These elastomers desirably have a JIS A hardness of 60 to 90 as measured according to JIS K6301.
(FR)
Tuyau comprenant une couche interne (1) et une couche externe (2) entourant la périphérie de ladite couche interne. La couche interne est constituée d'un élastomère oléfinique thermoplastique comprenant du polypropylène (PP) et un caoutchouc acrylonitrile/butadiène (NBR), et la couche externe est constituée d'un élastomère oléfinique thermoplastique comprenant du polypropylène (PP) et un caoutchouc éthylène/propylène/diène (EPDM). L'élastomère constituant la couche interne contient de préférence 1 à 5 % en poids d'un stabilisant renfermant un composé amine ou un mélange d'un composé thioéther avec un composé phénol encombré. Ces élastomères ont de préférence une dureté JIS A comprise entre 60 et 90 selon les mesures effectuées d'après la norme JIS K6301.
