Porous PTFE Plastic Polymer

Polytetrafluoroethylene (PTFE) is a versatile polymer used in a broad range of medical, industrial, and high technology applications. Porous PTFE is inert, making it unreactive to most chemicals, and, it can work in high processing and operating temperature environments (500°F / 260°C continuous).

Porex porous PTFE offers excellent thermal, electrical, mechanical, and chemical properties as well as superior control over pore size, permeability, water entry pressure, and thickness. PTFE is an ideal choice for a wide variety of demanding applications requiring one or a combination of these exceptional properties.


PTFE materials are manufactured in Class 100k clean rooms under ISO 9001:2008 quality standards. They are available in a variety of formats including rolls, sheets, die cut, and rotary cut parts and also with adhesive backings.
