Porous Vacuum Components

Porous Vacuum Components

Excellent performance with porous vacuum component

  • Ensure purity–Material is backed by the Certified Pure POREX™ program of independent laboratory testing of leachables, extractables and interfering substances.
  • Deliver precise flow rates and tolerances–Engineered for tight pore size and volume control.
  • Improve device effectiveness–Design is customizable per application and can incorporate anti-static properties.

Manufacturers around the world trust our porous materials to deliver excellent performance when used as vacuum components. Anti-static additives can also be introduced for applications that require conductivity.


Low Dielectric Material

Telecommunications

Lower energy absorption for high-frequency applications

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.
