HDPE Geomembrane Sheet

 

1. Products Description

High Density Polyethylene (HDPE) is the high density version of PE plastic and is harder and denser than the LDPE, but is less ductile, and lighter than water. It's playing an important role to prevent the air and groundwater pollution. The best thing about the HDPE is that it can be easily moulded and welded together and the use of UV Stabilizers improves its weather resistance. HDPE Geomembrane lives up to the expectations which are demanded in today's world of environmental engineering. And another important thing is: it is recyclable.

2. Features: 2.1 Low Permeability - HDPE lining systems are secure because leachate does not penetrate them; methane gas will not escape from the HDPE cover system; and rainwater will not infiltrate an HDPE cap.

2.2 Chemical Resistance - HDPE, resistant to a wide range of chemicals, is not threatened by typical solid or hazardous waste leachates. It is also suitable for sludge and secondary containment around chemical storage facilities.

Ultraviolet Resistance - HDPE's resistance to UV exposure is further enhanced by the addition of carbon black. Additionally, with the absence of plasticizers, volatilization is not a problem.

2.3 Reflective Factor - Poly-Flex offers its HDPE geomembranes in white as well as black. A white surface helps mitigate liner temperature extremes and aids visual inspection.
