About SealEco GreenSeal EPDM: During production, the EPDM is vulcanised (cured under pressure and heat) creating an elastic, chemically stable product with negligible aging through exposure to UV-radiation, atmosphere, chemicals, earth, water, and extremes of temperature. In contrast to plastic, this rubber membrane is highly elastic, and it can be elongated up to 300% without changing the properties, giving minimal risk for leakage. SealEco GreenSeal EPDM is also chemically stable and does not contain any softeners or other chemicals harmful to the environment. This pond liner material has the same physical characteristics as Butyl with a cost saving of some 30%. SealEco Greenseal EPDM pond liner is used extensively by landscapers and civil engineers for ponds, lakes, canals, and reservoirs. The largest pond liner sheet size (made to order) in one piece is 1800m2. Along with this 0.75mm thick liner, it is also available to order in 1mm thickness. Box-welded liners are also available to order using this type of liner.
