Dual Elastomer EMI/RFI Shielding Gaskets

Electrically Conductive Ultra-Vanshield® Dual Elastomer EMI/RFI Shielding Gaskets

The challenge for the RFI/EMI industry has been to create a highly conductive shielding gasket that maintains its mechanical integrity long-term. Dual Elastomer ULTRA-VANSHIELD® is definitively the unique solution to this problem. Each style incorporates design features not commonly found in other forms of shielding gaskets. Some of the more important advantages to consider are :
  • Continuously extruded high-strength silicone rubber core
  • Co-extruded highly conductive metal-filled silicone outer layer
  • Extremely high shielding effectiveness
  • Environmental sealing
  • No compression set
  • Low compression force
  • Extreme environment and abrasion-resistant options
  • Simple installation options
Traditional single elastomer MIL standard shielding gaskets to MIL-DTL-83528 are available as well.
Elastomeric Extrusions and Moldings

Elastomeric Extrusions and Moldings

Our focus is on engineered high-performance elastomers, such as silicone, fluorosilicone, fluorocarbon (Viton®, Fluorel®, etc.), EPDM, nitrile, conductive, sponge, and many other technical rubbery materials. We begin with in-house custom compound development paying close attention to your individual requirements of physical properties, finished part quality, and cost parameters. If needed, we will design the seal or gasket for you; or, work with your current designs. We then fabricate your extruded or molded article to the most exacting tolerances.

Van-Therm® Heat Conducting Elastomers

Van-Therm® Heat Conducting Elastomers

Van-Therm® is a highly efficient heat conducting interface material with wide application uses for electronic, electrical and electro-mechanical assemblies. Miniaturization and higher speed electronics demand efficient thermal management for reliable operation and long-term aging properties of all types of components. Space restrictions compound such considerations, and of course, cost containment is always a requirement.

Van-Therm®’s efficient thermal conductivity and conformability accommodate most component surfaces and substrates.
  • Conforms to irregular surface depressions and protrusions for maximum surface contact, and therefore efficient thermal transfer.
  • Material consistency permits high levels of heat extraction from heat generating components to heat sinks, thermal bridges and chassis members.
  • Ideal durometer allows greater controllable compression squeeze enabling highest heat conduction per minimum cross sectional area of thickness. See charts at left.
  • Available in strips, sheets and die-cuts for universal applications and specific standard or custom dimensions.
  • Custom extruded profiles and shapes available. Choose 70-XXX for more information.
