DESCRIPTION (top)  
     
  The Platon Membrane is manufactured from black or clear "high density" polyethylene (PEH). It is impermeable and resistant to the usual chemicals in the building construction. Square shaped studs are formed in a regular pattern on the one face of the Membrane, and spaced at approx. 25 mm centres. The product is supplied in rolls of 20 m in length.  
  With the exception of 1 m wide rolls, rolls of the product are supplied with an area without formings along one of the edges of each width. This edge acts as the finish at the top edge on external basement walls, such that the edge is pressed against the wall on backfilling and this prevents fill materal from entering the air gap. When the product is used as Separation Board, the edge forms the overlap over the next roll width.
  
     

 

 WORKABILITY (top)  
     
  The Platon P5 Membrane is tough but pliable and can be bent round corners and projections without risk of breaking even in very low temperatures. The Membrane can be easily cut with a knife or scissors.  
     

 

 STORAGE (top)  
     
  Rolls of Platon Membrane should be stored upright when stored over long periods.

 CHEMICAL RESISTANCE (top)  
     
  The Platon Membrane is resistant to all chemicals, to which it can be exposed, in normal building construction.  
  A small number of aggressive chemicals (e.g. solvents), in large concentrations, can to some extent attack the Platon Membrane during prolonged exposure. If the product is to be applied, for example as cladding to storage tanks for aggressive chemicals, the supplier should be contacted, with a view to assessing necessary action.
