Advantages

Ultra-Vanshield Dual Elastomer Shielding Gaskets Provide the Following Advantages Over Traditional EMI Gaskets with Conductive Particle Throughout Cross Section

  • Resilient inner core remains free of metal fillers
    • Optimum compression and aging properties
  • Silver conductive material is only present in outer thin membrane
    • Excellent Conductive Properties
  • Thin silver layer permits reduction in costly silver content
  • Attenuation performance is not degraded under full compression
  • Very low compression force
  • Manufacturing flexibility
  • Easy termination
  • Single piece weather and EMI seal
    • Extended galvanic protection
    • NEMA, IP, wind driven rain, and immersion sealing protection

Microbridge™

(US Patent # 6,410,846B1 and 6,613,976B1, other patents pending)

  • Same advantages as Ultra-Van Shield
  • Offers moisture seal on both sides of conductive portion for extended galvanic protection
  • Further reduces silver content for better cost performance

Comparison of Ultra-Vanshield and Microbridge vs. Traditional EMI Shielding Gaskets

Versus Meshes, Ultra-Vanshield and Microbridge have:

  • Lower compression force
  • Lower percentage of compression needed
  • Environmental sealing Higher shielding level
  • Self terminating

Versus Traditional Filled Conductive Elastomers, Ultra-Vanshield and Microbridge have:

  • Lower compression force
  • Lower percentage of compression needed
  • Environmental and galvanic sealing
  • Comparable shielding level
  • Improved compression set, tear, and crack resistance
  • Better aging

Versus Spring Finger Gaskets, Ultra-Vanshield and Microbridge have:

  • Lower compression force
  • Lower percentage of compression needed
  • Weather sealing
  • Comparable shielding level
  • Easier to work with: won’t cut hands; can cut with scissors
  • No maintenance necessary

Versus Fabric Over Foam, Ultra-Van Shield and Microbridge have:

  • Low compression set
  • Broader temperature range
  • Higher level of shielding
  • Weather sealing
