Elkamet manufactures thermoplastic liners of various sizes using rotational and extrusion blow moulding processes.

These are used, among other things, as the inner shell of pressure vessels for storing gases and liquids. Typical applications include hydrogen and CNG tanks. The thermoplastic liner serves as the inner shell. Mechanical strength is achieved with the aid of fiber and resin wrapping. One or more Boss parts are used as valve connections.
