    Materials Features
    Characteristics

    Porous PTFE represents a competitive alternative to the expanded e-PTFE and it is characterized by the following main properties:

    • Air flow rates: up to 20 l/hr/cm² at 20 mbar
    • Water intrusion pressure (WIP): up to 1,2 bar
    • Average pore diameter: up to 50 μm

    Applications & Uses

    Uses

    It is mainly used for the production of filters (dust and water purification filters as well as precision filters for medical/clinical and life science applications ), optical parts (reflectors, spectrometers, photometers), acoustic / sound dampening components (wind screens for microphones, air regulator for speakers) and electrical / electronic insulating items.
