AquaProof

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 )

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 50C 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

2. UV transparent
3. resisting against all acids and lyes, 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

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
