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-Vanshield™
  • Offers moisture seal on both sides of conductive portion for extended galvanic protection
  • Further reduces silver content for better cost performance
