Abstract: A first plastic recyclate is used for a tube of a land vehicle, in particular of a road vehicle. The tube comprises a first layer and a second layer, wherein the first layer and the second layer abut against each other. The first layer has the first plastic recyclate, wherein the second layer comprises a first virgin plastic. The first plastic recyclate and the first virgin plastic belong to the same plastic species, for example to the plastic species of polyamides or the plastic species of polyolefins.

Abstract: Multilayer motor vehicle tube for conducting at least one fluid medium, wherein the tube comprises a fluid duct and a tube wall that surrounds the fluid duct. The tube wall is multilayered and comprises at least three layers, specifically having the following layer composition. An external layer is provided that consists of at least one polyamide, in particular of at least one aliphatic polyamide. Furthermore, an adhesion-promoting layer is provided and an internal layer consisting of at least one thermoplastic elastomer. At least one barrier layer is also provided that consists of at least 96% by weight of polypropylene. The overall layer thickness d of the tube wall is from 0.3 to 3.0 mm.

Abstract: A tube and use of a tube for guiding hydrogen, preferably in a vehicle. The tube encloses a lumen and comprises several layers, wherein the layers of the tube includes at least two barrier layers. An inner barrier layer comprises a first plastic, and an outer barrier layer comprises a second plastic. The barrier layers are separated from each other by a separating layer, and the tube has a supporting layer enclosed by the inner barrier layer. The first plastic is a vinyl alcohol plastic, and the second plastic is a vinyl alcohol plastic.

Abstract: Multilayered motor vehicle tube, wherein the tube has at least five layers with the following layer structure from the outside to the inside: An outer layer made of at least one polymer from the group “polyamide, polyolefin,” a first carrier layer made of polyamide, a barrier layer made of at least one component from the group “ethylene vinyl alcohol copolymer (EVOH), fluoropolymer,” a second carrier layer made of polyamide, an inner layer made of a thermoplastic polyurethane (TPU). The total layer thickness of the tube is 0.7 to 2 mm.

Abstract: Use of tubing as temperature control tubing in motor vehicles, wherein a temperature control medium is passed through the tubing. The tubing has the following layer structure from the outside inward: an exterior layer of at least one polyolefin, a first adhesive barrier, a barrier layer of at least one polyamide, a second adhesive barrier and an interior layer of at least one polyolefin. The entire wall thickness of the tubing is 0.5 to 3.5 mm.
