HDPE Geomembrane
HDPE Geomembranes are thin two or three-dimensional sheets with very low permeability. The polymers come from a chemical plant in the shape of granules. During further processing, the granules are melted and after extrusion, eventually followed by spinning, the semi-manufactured products get the shape of sheets. The additives can be used during melting before extrusion. These additives have the main purpose of improving the less favorable properties of the basic materials, especially the sensitivity for alterations.
