Manufacturing technology

The heart of the liner production is the patented, self-developed circular loom by Primus Line.

With its high-precision electronic controls it weaves a seamless and twist-free hose out of aramid fibre, or a blend of aramid and polyester fibre.

This sets the foundation for the extrusion process that applies the inner and outer layers which are based on polyethylene (PE) or thermoplastic polyurethane (TPU). The approximately 20 metres high vertical production line combines the three raw materials into a robust three-layered liner.

The technology is constantly improving and allows for the use of new plastics for the inner and outer layer. This offers the opportunity to optimize the liner even more or develop it further for entirely new areas of application.
