Abstract
The present invention relates to a fuel hose made from a metal-plated elastomer and to a method for its manufacturing.
Claims19
A hose comprising at least one layer L, said layer L being made from a composition comprising at least one elastomer and having an internal surface (Si) and an external surface (Se-NM), said surface (Se-NM) comprising nitrogen-containing groups (N) and at least one metal compound (M).
A method for manufacturing a hose, said method comprising:
- processing a composition (C), wherein composition (C) comprises at least one elastomer, so as to provide a hose having an internal surface (Si) and an external surface (Se);
- forming nitrogen-containing groups (N) onto said surface (Se) so as to provide a hose having a nitrogen-containing external surface (Se-N);
- contacting said surface (Se-N) with a composition (C1), wherein composition (C1) comprises at least one metallization catalyst, so as to provide a hose having an external surface (Se-NC), wherein surface (Se-NC) contains groups (N) and at least one metallization catalyst;
- contacting said surface (Se-NC) with a composition (C2), wherein composition (C2) contains at least one metal compound (M1), so as to provide a hose having an internal surface (Si) and an external surface (Se-NM), said surface (Se-NM) comprising groups (N) and at least one compound (M).
