RFI EMI Shielding Elastomers

VANGUARD ULTRA-VANSHIELD® DUAL shielding elastomers offer the optimum combination of metallic conductivity and elastomeric performance.

• Resilient inner core remains free of metal fillers, resulting in optimum compression and aging properties.

• Silver conductive material is only present in the outer thin membrane, resulting in excellent conductive properties.

• Thin silver layer permits reduction of costly silver content required.

• Attenuation performance is not degraded under full compression as with solid-filled elastomers.

• Very low compression force and resistance to deformation.

• Manufacturing flexibility and quick turnaround of custom designs. Viable short run alternative.

• Easy termination. No requirements for end treatment.

• Available with a variety of optional conductive metals.

We offer a wide range of EMI/RF shielding solutions from world leading manufacturers.

  • homogenius silicon gaskets, such as SuperShield, Multishield, Monoshield Weaveshield,
  • conductive foam
  • gasket for connectors
  • fabric over foam gaskets  from world leading manufacturers.

Ultra-Vanshield® Dual-Elastomer gaskets from Vanguard

Each style incorporates design features not commonly found in other forms of shielding elastomers and gaskets. Some of the more important advantages to consider are:

  • Continuously extruded high-strength silicone rubber core
  • Co-extruded highly conductive metalfilled silicone outer layer
  • Extremely high shielding effectiveness
  • Environmental sealing
  • No compression set
  • Low compression force
  • Extreme environment and abrasionresistant options
  • Simple installation options

MicroBridge gaskets from Vanguard

Microbridge® is the ultimate construction design utilizing new technology which creates a microscopic conductive bridge through the body of an elastomeric extruded gasket. The conductive element traces a path, by putting the conductor only where it is needed through the interior of the silicone rubber core, yielding very significant cost- effective savings of the conductive material.

This leaves the outside face of the mounting surface side with as much adhesion-active area as possible and improved galvanic corrosion resistance with low compression/ deflection forces. Excellent for I/O backplanes and all general RFI/EMI shielding applications.

Available in most profiles in this catalog and many custom configurations. Be creative and utilize our design staff to help optimize your specific application. Standard tooled profiles: strips, D-bulbs and T-wiper styles. Custom layouts of the conductive traces and die-cutting are easily arranged (see also custom die-cuts below).
