Features Durability
Aztex Membrane will remain flexible and will not degrade or oxidise under temperature conditions likely to occur in practice: Their effective operational temperature range is -25°C to 60°C. Chemical Resistance
Aztex Membrane is resistant to attack by inorganic acids, alkalis, salt solutions which cause corrosion to metals, and dilute solutions of detergents or bleaches. Resistance to U.V. Light
Exposure to ultraviolet light, including sunlight, will embrittle Aztex Membrane. The material is not therefore recommended for uses where it will be exposed to long periods of outdoor weathering. However, weathering will not occur when the
membrane is installed in accordance with the recommendations. Resistance to Puncturing
Aztex Membrane conforming to this standard has a high resistance to puncturing, when used in accordance with the recommendations. However, care should be taken to avoid damage during handling, storage, installation, and when covering with screeds or concrete. Typical Dimensions
Typical dimensions and corresponding minimum nett reel weights are:
4m x 12.5m x 50μm - 23.0kg Dimensional Tolerances
Length: -0 +10% of labelled length
Width: ±2.5% of labelled width
Yield: (The area of the sheet may be used to calculate the weight of the reel as follows, assuming a film density of 920kg/m3) 500 micron sheet yields 2.17m2/kg. Tear Resistance
The tear resistance of the damp proof membrane shall be not less than the values shown below:
Tear strength: (N) 20
Tear strength: (N/mm) 40 Impact Strength
When measured six hours or more after extrusion, the value obtained shall not be less than the values shown
below:
Impact strength-body; (F50,g) 1000
Impact strength-fold; (F50,g) 500 Tensile Strength
The tensile strength of Aztex Membrane shall not be less than the values shown below:
Tensile strength; (N/25mm) 180
Tensile strength; (MPa) 14.4 Elongation at Break
The breaking elongation (unaged) of all thicknesses of Aztex Membrane shall be greater than 500%. When subjected to accelerated ageing (56 days @ 80°C) the breaking elongation shall be greater than 250%.
