DESCRIPTION (top)  
     
  The Platon P20 Membrane is manufactured from black high-density polyethylene (PEH). It is impermeable and resistant to the usual chemicals in the building construction.  
  When the product acts as a damp proof membrane, both the product and floor coverings may be installed independent of the moisture content in the underlying concrete construction and with running water not under pressure in the air gap.  
  Studs are formed in a regular pattern on the one face of the Membrane. The studs are spaced at approx. 60mm centres. The product is supplied in sheets dim. 2230 x 1360mm and rolls 19.5m x 1.36m.
  
     

 

 WORKABILITY (top)  
     
  The Platon P20 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)  
     
  Sheets of Platon P20 Membrane should be stored flat and rolls of P20 Membrane should be stored on end.

 CHEMICAL RESISTANCE (top)  
     
  The Platon P20 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 P20 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.
For normal applications of the Platon P20 Membrane, relevant aggressive chemicals are very volatile, because of their very nature. This means that if they should come in contact with the Platon P20 Membrane, following an accident, they will evaporate of flow away from the construction without permanent damage occurring.
