Porelle Hydrophilic membrane
Porelle hydrophilic membranes are available in 3 different technology options: polyurethane, TPU and cross-linked membranes.
Porelle hydrophilic membranes have a solid structure that physically stops water passing through the membrane. They breathe by absorbing and dissipating sweat through the diffusion of water vapour molecules. The chemical structure of the membrane is made up of hydrophilic (water loving) groups that attract water vapour molecules. Driven by greater heat and water vapour density, the water vapour molecules move from one hydrophilic group to the next (somewhat like stepping stones).
Porelle hydrophilic membranes are available in different thickness options ranging from 12 to 40 microns.
