MAJR Products - Metallized Filled Silicone (5000 Series)

Conductive Metallized Filled Silicone Elastomers

General Descriptions

Metallized Filled Silicone is a molded silicone elastomer filled with conductive inert particles. It provides high electrical conductivity, broadband shielding and moisture sealing. MAJR offers these elastomers filled with:

Nickel Graphite (52)
Nickel (60)
Silver-Plated Glass (61)
Silver-Plated Copper (62)
Silver-Plated Aluminum (63)
Silver-Plated Aluminum FluoroSilicone (64)
Silver-Plated Nickel (65)
Silver (66)

Metallized Filled Silicone is designed to provide reliable and cost-effective shielding for a wide range of EMI
applications. Metallized Filled Silicone is manufactured in sheets, molded parts, strips and die-cut flat gaskets.

Application Information

Metallized Filled Silicone should be used where there is a need for high broadband shielding combined with excellent moisture-sealing properties.

In order to assure electrical conductivity and sealing reliability, recommended design compression is 7% - 15% of original height for sheets and rectangular strips. For “O” and “D” shapes the recommended compression is 12% - 30%.

Adhering and Joining

For splicing, joining and bonding Metallized Filled Silicone gaskets to enclosures, MAJR recommends a two-component, electrically conductive, silver silicone adhesive sealant of medium viscosity. This material provides a flexible bond and a resilient seal. If necessary, MAJR can provide this sealant with your order; ask your representative.

EMI Shielding Performance*

MAJR’s Metallized Filled Silicone Shielding Effectiveness has been tested in accordance with MAJR’s Test Methods and based upon modified MIL-STD-285. Typical Shielding effectiveness values are based on a 5˝ square aperture.

MAJR’s Metallized Filled Silicone Shielding Effectiveness has been tested in accordance with the test method described in paragraph 4.6.12 of MIL-DTL-83528. Typical values are shown:
