PRODUCT DETAILS
Geomembrane manufacturer in China
Introduction ；
Smooth HDPE Geomembrane is manufactured from High Density Polyethylene resin with proportional carbon black antioxidant, anti-aging and UV-resistance supplies by way of the use of the science of coextrusion-blown triple layer. The surfaces of every sides are smooth,Geomembrane is a geoimpermeable material made of plastic film as impermeable substrate. It is a water resistant setting up fabric which is impermeable and moisture-proof. Its impermeable property specially depends upon on the impermeable property of plastic film.
Geomembrane materials and characteristics The main feature of geomembrane;
Is very low water permeability, so the primary substances for the manufacture of geomembrane are basically polymers with low water permeability, asphalt and artificial fibers and fabrics, in addition, there are positive fillers and admixtures. Such as: polyvinyl chloride (PVC) chlorinated polyethylene (CPE) high, medium and low density polyethylene (HDPE, MDPE, LDPE) plastics; Butyl rubber (IIR) propylene oxide rubber (ECO) Neoprene rubber (CR) rubber; Ethylene propylene (EPDM) ethylene vinyl acetate (EVA) combined class. Admixtures consist of plasticizers, anti-aging agents, antibacterial agents, more than a few stabilizers and so on.
