MIL-DTL-83528/4 EMI Flange Gaskets
MIL-DTL-83528E Type B Material:
Silver-plated, aluminum-filled silicone capable of 100 dB of plane wave shielding effectiveness at 10 GHz with a continuous use temperature range of -55°C to +160°C.
Example PIN: M83528/004B001
• M83528 - indicates the EMI / RFI family of conductive materials
• 004 – indicates the flange style
• B – indicates the specific material type (B indicates Ag/Al filled silicone)
• 001 – indicates the size and exact dimensions of the conductive flange gasket
How are MIL-DTL-83528E Type B Gaskets made?
Stockwell Elastomerics manufactures EMI gaskets from a range of processes including, compression molding, waterjet cutting, tool-less flash cutting, and die cutting. These capabilities allow Stockwell Elastomerics to mold Type B EMI sheets and cut MIL-DTL-83528/4 gaskets with very little waste.
MIL-G-83528 Gasket Materials and Non-Mil Options
MIL-DTL-83528/4 points to Mil-G-83528 which defines material type and performance requirements. The mil spec can be restrictive from a design perspective - for example, hardness is limited to 65 durometer or expensive conductive particles (silver) are required. For EMI applications not requiring MIL-G-83528 EMI materials, Stockwell offers non-mil spec EMI materials that have been third party tested per Mil-G-83528 for attenuation performance. Materials include softer EMI rubber for lower compression force, EMI gasket material with passivated silver/aluminum for better corrosion resistance and nickel graphite filled conductive rubber to reduce cost.
