THERMOPLASTIC MULTILAYER WATER TRANSMISSION TUBE

摘要

In a water transmission tube made of a thermoplastic and having a wall comprising at least two layers, the outer layer consists of a polyolefin material and the inner layer consists of a thermoplastic which is admixed only with substances required for processing it and which as such has no bacterial growth-promoting activity. The inner layer preferably consists of a thermoplastic which is selected from the group consisting of polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC), thermoplastic polyurethane (PU), acrylonitrile-butadiene-styrene (ABS) and polyethylene terephthalate (PET), and is preferably less permeable to organic substances than the outer layer.
