1 ElectroSeal Conductive Elastomer Material How to Specify EcE Decide on molded sheet stock or extruded shapes. Select the desired configuration and dimensions from Table 1 (for sheet stock) or Figures 1 8 (for extruded shapes). Select the desired material from Table 2. Insert material number from Table 2, pages 14 16, in place of the letters XX in the Laird Technologies part number. Example 1. From Figure 1, on page 18, for a rectangular strip measuring in. (12,7 mm) x in. (1,9 mm), part number is XX. 2. From Table 2, on page 16, for silver-nickel filler, material number is Ordering part number is * Note: Rectangular and D-shaped extrusions can be supplied with pressure sensitive adhesive tape. ElectroSeal Conductive Elastomer EMI Shielding Laird Technologies electrically conductive elastomer products are ideal for both military and commercial applications requiring both environmental sealing and EMI shielding. Compounds can be supplied in molded or extruded shapes, sheet stock, custom extruded, or die-cut shapes to meet a wide variety of applications. *If pressure sensitive adhesive is required, replace the fifth digit with a 9 (i.e ). Our conductive extrusions offer a wide choice of profiles to fit a large range of applications. The cross-sections shown on the following pages are offered as standard. Custom dies can be built to accommodate your specific design. vailable in a wide variety of conductive filler materials Shielding effectiveness up to 120 d at 10 GHz Sheet Material Table 1 lists thicknesses and sizes for our molded sheet material, while Table 2, pages 14 16, shows the compounds available for all of our conductive silicone elastomers.
