Custom Porex PTFE Gaskets


Why Choose POREX PTFE Materials?

Porex PTFE Materials offer excellent control over pore size, porosity, permeability, water intrusion pressure and thickness. Designed to help deliver precision, accuracy and reliability, Porex PTFE Materials exemplify the critical design standards required in many challenging filtration, venting, diffusion and media support applications.

Porex PTFE feature an intricate network of open-celled, omni-directional pores that offer exceptional performance on and below the surface. The proprietary manufacturing process results in a robust, durable, chemically resistant and design flexible material with long-term value advantages. POREX® porous PTFE offers excellent thermal, electrical, mechanical, and chemical properties.
