Porous ptfe grades are produced from suspension ptfe powders and specifically they are a mixture of different particle size distributions and hardness degrees to achieve the desired level of porosity.
Taking advantage of the up-to-date technologies and know-how used to process sintered ptfe products, Guarniflon® has developed different grades of porous ptfe with the following main properties:
- Air flow rates: up to 20 l/hour/cm2 mbar
- Water intrusion pressure: up to 1.2 bar
- Average pore diameter: up to 50 µm
