1. AquaProof A barrier liner for various applications

2. 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 )

3. The construction first EPDM layer PTFE foil PTFE foil treated final EPDM layer

4. 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

5. 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

6. Aquaproof is: 1. UV stabile 2. UV transparent 3. resisting against all acids and lye’s, especially also against brines 4. stabile against all kind of enzymatic reactions of micro- organisms 5. an antifouling material 6. watertight 7. airtight 8. barrier for water, oil, petrol, gasoline etc

7. 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
