Yixing Shenzhou 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. HDPE
Smooth Geomembrane ( YIXING SHENZHOU) is a smooth high-density
polyethylene (HDPE) geomembrane manufactured with the highest
quality resin specifically formulated for flexible geomembrane.
HDPE Smooth Geomembrane is the preferred product for lining
projects requiring low permeability, chemical, and ultraviolet
resistance properties, which makes them extremely cost-effective
for many applications.
