We offer all standard market membranes with properties wind-, waterproof and highly breathable, basically PTFE and PU membranes:
PTFE, short for polytetraflourethylene, especially suits laminates with extreme requirements concerning waterproofness after ageing and cooling.
It has nearly universal chemical resistance and temperature restistance from -240 to +250°C.
It is microporous, which means, water vapur may diffuse through the membrane in form of molecules.
PU (polyurethane) membranes in contrast have a much higher elasticity and are hydrophilic. Water vapour may diffuse due to a chemical migration process.
