Mesh Strip

MESH STRIP gaskets are compressible, all-metal EMI/EMP strips knitted into rectangular or round cross sections. The knitted wire forms many spring-like interlocked loops, making it highly resilient. Standard MESH STRIP gaskets are knitted from either monel (a nickelcopper alloy) or Ferrex* (tin-plated, copper-clad steel) wire.

Chomerics also provides SPRINGMESH gaskets, special allmetal spring wire knitted mesh strips in a hollow tube shape with compression- deflection characteristics of 70- 80%.

Other metals and alloys (such as aluminum mesh) are available. Monel is used most frequently due to its good aging properties, excellent tensile strength, and spring-like qualities. Ferrex offers the best EMI shielding performance, especially in H-fields, but has limited corrosion resistance.

All-metal MESH STRIP gasketing cannot provide a pressure or weather seal, and is not recommended for joined gaskets smaller than 2 in. (50.8 mm) x 2 in. (50.8 mm), or 3 in. (76.2 mm) in diameter.

Round cross-sectional gasketing is available with fins which simplify mounting by either riveting, spotwelding, or suitable structural adhesive bonding. The rectangular and round MESH STRIP gaskets can be held in grooves or slots by sidewall friction.

MESH STRIP gasketing is supplied on spools in continuous lengths, or can be formed into ready-to-use, one-piece fabricated gaskets.

Standard MESH STRIP – Order by part numbers listed in Tables 2-5 (on page 2), and specify total length required.

Fabricated MESH STRIP Gaskets – Specify material by part number in Tables 2-5. Submit a drawing of the required gasket shape and dimensions. Tolerances for fabricated gaskets are as follows:

0 – 4.9 in. ±0.03 in. (0 – 125 mm ±0.76 mm); 5.0 – 10.0 in. ±0.06 in. (127 – 254 mm ±1.52 mm); over 10.0 in. (over 254 mm) ±6%. Custom MESH STRIP shapes are also available.
