Mesh Strip with Elastomer Core Gasket
Standard MESH STRIP gasketing with elastomer core consists of two layers* of wire mesh knitted around a rectangular or round core of neoprene or silicone. The knitted wire mesh provides the electrical conductivity for EMI/EMP shielding, and the core provides excellent compressibility with a high degree of resilience. Closing force is in the 50-100 psi (0.34-0.69 MPa) range.
Elastomer core MESH STRIP gasketing does not provide pressure sealing, but it does provide a seal against dust, rain, ventilating air and other limited environmental conditions.

Elastomer core MESH STRIP gasketing does not provide pressure sealing, but it does provide a seal against dust, rain, ventilating air and other limited environmental conditions.
The standard wire materials are monel (a nickel-copper alloy) and Ferrex** (tin-plated, copper-clad steel). 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.
Standard core materials include neoprene sponge (MIL-R-6130, Type II), hollow solid neoprene (MILR- 6855, Class II), closed cell silicone sponge (AMS-3195) and solid silicone hollow tubing (ZZ-R-765, Class 2B).
In addition to the standard configurations listed, almost any elastomer core cross section can be produced, including UL 94V-0 rated core materials.
Also see SPRINGMESH gaskets, an all-metal spring wire hollow tube design with compression-deflection characteristics of 70-80%.
Ordering Procedure
Order by part numbers listed in Tables 2-6 (on page 4), and specify total length required. Gasketing is normally supplied on spools in continuous lengths.
Note: Elastomer Core MESH STRIP gasketing is not easily joined into single-piece gaskets. For this reason, gasketing should be factory fabricated to customer specifications.
Fabricated Gaskets – Specify materials by part numbers from Tables 2-6. Submit a sketch of the required gasket dimensions. If possible, include a brief description of the shielding/sealing application. For additional design assistance, contact Chomerics’ Applications Engineering Department.
