An element for a conduction system in a fuel cell has an inner, conducted medium-contacting layer of a polyamide molding material together with >=1 further layer comprising a further polyamide, an optionally functionalized polyolefin or an EVOH copolymer.

Plastic tubing has inner layer (1) made of a first thermoplastic extruded plastic material such as ETFE or PVDF and outer layer(3) made of a second thermoplastic extruded plastic such as a polyamide. There is a middle layer between them made of a third the...

The present invention relates to a hose (110) comprising a rubber layer (111) and a polyamide barrier (112) layer overlaying the rubber layer (111). The rubber layer (110) is comprised of a rubber composition comprising from 70 to 90 parts by weight of a f...

A hose (10) comprising a core layer (12), an elastomeric friction layer (18) overlaying the core layer (12), at least one reinforcement layer (20) overlaying the friction layer (18), and a cover layer (22) overlaying the at least one reinforcement layer (2...

A corrugated polyamide tube comprises a corrugated outer layer (a) of polyamide resin, and a flat inner tube layer (b) of polyetheramide elastomer, where (b) is fixed to (a) at its bottom portion.

Tubing, especially charge-air tubing, with fluroelastomer inner layer(s) (1), a peroxide-crosslinked silicone elastomer layer (2), a reinforcing layer with strengtheners (3) and an elastomer outer layer (4), in which the inner layer (1) is crosslinked with...

A hose (10,10',10") suitable for use in refrigerant systems. The hose (10,10',10") has a barrier layer (14) formed of at least two layers of thermoplastic resin. At least one of the layers is a vinyl resin. The resins are selected so that the hose has a pe...
