Porex Low Dielectric Porous Material POREX®

High-frequency applications, such as antennae systems, require low energy absorption. Trusted by manufacturers around the world, our low dielectric materials:•Ensure purity and manufacturability-POREX Virtek™ PTFE is pure PTFE and does not require a backing or support scrim like expanded PTFE. This allows for assembly via heat or vibrational welding.•Deliver low dielectric constants-Offer constants as low as 1.4.•Surface structure allows printing or plating of metals.•Improve device effectiveness-Material can be made into two and three-dimensions shapes from a variety of substrates, plus the ability to trap functional additives or catalysts within the pore structure.

Porous plastic and fiber media are used extensively in numerous protective venting applications ranging from medical devices to industrial systems. Porous plastic protective vents offer distinct advantages over mechanical vents or physical openings since dust and moisture can be kept out, and there are no moving parts which can stick or only work in one direction. Manufacturers can choose from venting solutions customized by configuration, pore size, air flow rate, adhesion level, and material, as well as standard venting solutions across various materials. Porex can also add functionality to vents; for example, a self-sealing or color change can occur if the vent encounters moisture. If the application is complex, our development team can assist you in determining the most efficient way to meet your venting requirements.
