Water vapour permeability

Water vapour permeability is only measured for relatively impermeable materials such as films. A meaningful measurement value for LIGASANO® can therefore not be given, it is almost unhindered water vapour permeable. The usual measuring methods, e.g. according to DIN 53122, ISO 11092, DIN 31092, are not applicable.
This is also the reason why LIGASANO® should always be at least two centimetres thick when treating wounds (measured from the wound bed). So that too much air does not get to the wound, so that a temperature-insulating effect is created, so that exudate does not dry out and LIGASANO® does not stick to the wound.
