The tensile strength test and tear strength test of geomembrane are one of the important indicators to evaluate the mechanical properties of geomembrane materials. A geomembrane is a thin film material used to prevent the penetration of water, gas or chemicals. Common geomembranes include HDPE (high-density polyethylene), LDPE (low-density polyethylene), PVC (polyvinyl chloride), etc. Tensile

The installation difference between HDPE geomembrane and PVC geomembrane Material flexibility: PVC geomembranes are more flexible and malleable than HDPE geomembranes. This makes the PVC geomembrane easier to bend and fit to irregular surfaces and shapes during installation. HDPE geomembranes are relatively rigid and require more handling and welding operations to fit a particular structure
