Certifications Available:
- UL 50/UL 50E/UL 508: This standard applies to enclosures for electrical equipment intended to be installed and used in non-hazardous locations. It’s applicable to electrical equipment enclosures for indoor (Types 1, 2, 5, 12, 12K, and 13) and indoor/outdoor applications (Types 3, 3R, 3S, 3X, 3RX, 3SX, 4, 4X, 6, and 6P). This standard covers the construction and performance requirements for enclosures to provide a degree of protection to personnel against incidental contact with the enclosed equipment. This standard also covers additional environmental construction and performance requirements for enclosures. Our Ultra-Vanshield EMI shielding gaskets are listed by UL for use within this standard (UL File Number MH48850).
- UL94: This standard covers flammability of polymeric materials used for parts in devices and appliances. It is intended to serve as a preliminary indication of their acceptability with respect to flammability for a particular application. We have numerous products that are rated as UL94V0, among the highest level of flame retardancy. (UL File Number E31158)

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
