CSPE (Hypalon) demonstrates excellent durability against UV and Ozone exposure and resistance to a wide variety of organic and inorganic chemicals. CSPE liner will retain flexibility in freeze/thaw conditions and will resist the elements better than any known material. It's resistance to oxidation and immunity to ozone and UV make it a lining choice in potable water and some industrial waste applications (that don't contain fats oils or hydrocarbons), floating covers and exposed lagoons.
CSPE is a reinforced flexible geomembrane with an exceptional service life. It is a synthetic rubber product manufactured by the calendar process into plies that are combined over reinforcing polyester scrim layer or layers during manufacture. It is available in up to 5 ply layers (with two reinforcing layers) making it an excellent choice for steep slopes and dam lining applications.
CSPE Liner is heat welded under controlled conditions into panels at one of CLI's 3 fabrication facilities, and field seamed using either heat welding or solvent adhesives. CSPE is available in 36, 45 and 60 mil thicknesses and up to 90 mils by special order. CLI fabricates CSPE in panels of up to 25,000 sf.
Pre-fabricating panels allows the deployment and installation of large quantities of liner. Field seaming uses either heat welding or a bodied solvent adhesive (following a pre-wash) to give equally reliable results under the varying weather conditions encountered during installation. After installation, a surface cross-linking develops which produces a stronger, tougher, and weather able liner.
CSPE based flexible membranes are used in a broad range of applications and weather conditions and have an extremely long service life. High performance CSPE synthetic rubber products are available for construction and industry. CSPE is exceptionally resistant to oxidation and is virtually immune to ozone and UV proving it to be a suitable containment geomembrane for a large variety of industrial wastes.
