Geomembranes CSPE
Elastomeric and Bituminous Geomembranes

Chlorosulfonated polyethylene (CSPE) is not a separate polymer. It's actually a polyethylene to which chlorine and sulfur chloride have been added. These chemicals added to polyethylene have two effects:

• they prevent crystallinity, resulting in an amorphous, rubbery product;

• they facilitate vulcanization .

There are a variety of CSPE formulations with different chlorine contents. Higher chlorine content gives higher chemical resistance and lower mechanical...
