... New guidelines in the United States to prevent the buildup of electrostatic charges in the fuel system necessitate the development of filling pipes that are able to discharge static electricity. For this purpose, special PE-HD grades (e.g. Hostalen GM 9350 C black) have been developed. They are used predominantly as an inner lining for coextruded filling pipes, manufactured by the 3D blow moulding process.

Improved PE100 grades, such as multimodal Hostalen pipe grades by the ACP process now allow the production of large, thick-walled pipes with a uniform wall-thickness distribution. New pipe concepts with multilayer structure, or so-called functional layers have also helped to expand PE-HD’s position. ...
