Diffusion Tubes

Enhance semiconductor processing with pure materials

Our high-purity diffusion tubes allow semiconductor processing facilities a precise way to diffuse, filter and distribute process gases.

Specifically designed to precise flow and dimensional tolerances, POREX® diffusion tubes:

• 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 process effectiveness–Design is customizable per application requirements.

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.
