Porelle Microporous Membranes
Porelle microporous membranes are based on a polyurethane chemistry and are constructed from many small interconnecting micro pores less than 1 µm in diameter
.
Porelle microporous membranes are hydrophobic (water hating) and resist the passage of water, even under high pressure. At the same the membrane breathes by allowing sweat in the form of water vapour molecules to pass through the microscopic pores driven by greater heat and the higher density of water vapour molecules from the inside of the garment.

The unique combination of microstructure and polyurethane chemistry ensures that Porelle microporous membranes remain waterproof in use, even after repeated washes or steam sterilisation.
Porelle microporous membranes are available in thickness options: 30, 45 and 55 µm.
