Metallized Filled Silicone
Conductive Metallized Filled Silicone Elastomers
Metallized Filled Silicone is a molded silicone elastomer filled with conductive inert particles. It provides high electrical conductivity, broadband shielding and moisture sealing. The elastomers are filled with:
Nickel Graphite
Nickel
Silver-Plated Glass
Silver Aluminum
Silver-Plated Nickel
Silver
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 gasket.
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%.
For splicing, joining and bonding Metallized Filled Silicone gaskets to enclosures a two-component, electrically conductive, silver silicone adhesive sealant of medium viscosity is recommended. This material provides a flexible bond and a resilient seal. If necessary this sealant can be provided with your order.
Metallized Filled Silicone Shielding Effectiveness has been tested based on modified MIL-STD-285.
Board Level Shielding
We can provide design and production of custom board level shielding. The photoetching process allows the fabrication of parts with complex shapes and features that are impossible to duplicate by other methods without expensive tooling:
Improved flexibility of design
Can specify more intricate geometry
Shortens lead times
Forming tools not required
Mounting pin styles in any configuration
Through holes/slots for heat dissipation
Soldered or resistance welded seams optional
Custom fence/removable cover option
No limitation as to size or shape
Board level shielding is typically etched from .008" - .016" brass, nickel silver, copper or cold rolled steel. Board level shielding can also be manufactured out of beryllium copper, if spring qualities are desired. The standard finish is tin plate. Other finishes are available.
Depth-etch bend lines allow forming without tooling by the customer or the factory.
Samples available. If you need additional information or samples of board level shielding, call us today.
