EMI/RFI Knitted Wire Mesh Gasketing

shield_seal_gasketing3All mesh EMI/RFI knitted wire gasketing is available in various cross sections to satisfy the many different requirements encountered in shielding applications. The choice between rectangular, round, round with fin or double round with fin depends on the enclosure or equipment to be shielded.

Each strip has the same resiliency created by the knit construction but reacts differently dependent on material and shape. Of the most common materials used, Monel has the best spring factors while silver-plated brass has the highest conductivity. All mesh gasketing which is rectangular or round is recommended for grove mounting while single round with fin or double round with fin is recommended for flat surfaces. Surface conditions must be clean and free from such contamination as paint or oil for good conductivity and there should be an even distribution of pressure continuously along the length of the gasket.

A wide range of knit wire mesh materials are available. The standard knit wire mesh is either Monel or tin-plated ferrous. While these are standar, aluminum, silver-plated brass, gold-plated copper, tungsten, stailess stell, silver, nickel, iconel, and other wire can be knit and fabricated into special products.

Why Durlon® 8500 or Durlon® 9000?

durlon9000
Durlon® is gasketing material engineered to perform in a wide variety of applications. It’s ideal for applications involving high caustic, aggressive chemicals.

There are a number of Durlon® formulations but Durlon® 9000 and Durlon® 8500 are two of the most popular.

 

Durlon® 9000 has several attributes that separate it from other PTFE materials including:

  • Listed as an acceptable gasket material for Dry Chlorine service (both liquid and gaseous) in Pamphlet 95 of the Chlorine Institute.
  • Approved for Caustics services. Unlike generic glass fiber filled PTFE, the shape of the fillers used in DURLON® 9000 do not allow liquids to wick which can cause corrosion on flange faces.
  • Gaskets for oxygen service can be supplied from distributor stocks, providing proper cleaning procedures for oxygen service are followed before installation.

Durlon8500
Durlon® 8500 is one of our workhorse general service sheet gasket materials.

  • It is composed of both inorganic mineral and high strength aramid fibers with an NBR rubber binder.
  • It has passed the modified API 607 fire test.
