AquaProof A barrier liner for various applications
The layers • EPDM rubber (ethylene propylene diene monomer rubber) • high mechanical stability • good chemical stability (~10 years) • PTFE (polytetrafluoroethylene) skived foil • low mechanical stability • ultimate chemical stability ( for eternity )
The construction first EPDM layer final EPDM layer PTFE foil PTFE foil treated
What is the unique with such setup? • There a just 5 companies in the world which are able to etch PTFE = pulling fluorine atoms out of the PTFE molecule chains and destroying (etching) the surface up to a depth of about 20-30µm • 2 in the USA, 1 in Italy, 1 in UK and 1 in Germany • none of them is able just to treat (depth of 1-3µm) the surface of thin foils, what is necessary to laminate EPDM with PTFE • just the company POLYMADE in Germany is able to treat the surfaces of thin foils without destroying them • POLYMADE is part of the MS Licence group
Why such an effort ? • there are bacteria which are able to crack the C-C binding in anaerobic processes • soil temperatures of up to 50°C accelerating the micro-biological activities exponentially • what is stable in Europe for 20-30 years lasts in the Middle East not even 10 years • only PTFE cannot be attacked by bacteria due to the super-stable C-C bonding, sheltered by the fluorine atoms surrounding
Aquaproof is: UV stabile UV transparent resisting against all acids and lye’s, especially alsoagainst brines stabile against all kind of enzymatic reactions of micro-organisms an antifouling material watertight airtight barrier for water, oil, petrol, gasoline etc
AquaProof can be used as: • Golf Course lake liners • Recreational Pond liners • Aquaculture Pond liners • Canal Liners • Potable Water Reservoir liners • Secondary Containment • Roof liner • Barrier to prevent the trickle in of sea-water into the good garden soil
