Latest Patents

Lars Höjer holds a patent for the "Use of cross-linked polyolefins material in pressure pipes." This patent describes the use of at least partly cross-linked polyolefin plastic, which is oriented biaxially, as material for pressure pipes. The production process involves extrusion followed by axial and peripheral orientation of the pipe, with at least partial cross-linking occurring before the biaxial orientation. The preferred method allows for cross-linking to about 20-50% before orientation, enabling the process to be carried out at temperatures above the crystalline melting point of the plastic material.
