Conductive Elastomers

A Powerful Combination of Environmental Sealing (IP) and Military-Grade EMI Shielding

Conductive elastomers from Laird Performance Materials are designed to provide a dual-purpose solution: hermetic sealing against water, moisture, and dust, alongside exceptionally high electromagnetic shielding. These materials are compounds of Silicone or Fluorosilicone rubber integrated with conductive metal particles, creating a resilient gasket with excellent electrical conductivity throughout its entire structure.

Why Choose Laird Conductive Elastomers?

Laird’s solutions are considered the gold standard in the Defense and Aerospace industries due to several key characteristics:

• Maximum Shielding Performance: Attenuation of over 100dB at frequencies up to 18GHz and beyond, depending on the metallic filler type.
• Harsh Environment Durability: Excellent resistance to extreme temperatures, vibrations, and protection against fluid ingress with IP67/68
• Galvanic Corrosion Prevention: A wide range of fillers (such as Nickel-Graphite or Silver-Aluminum) allows for perfect chemical compatibility with the enclosure material (Aluminum, Stainless Steel, etc.) to prevent oxidation.
• Chemical Resistance: Options for a Fluorosilicone base ensure resistance to fuels, oils, and solvents—essential for aerospace and automotive applications.

Conductive Filler Types and Selection

The choice of the correct filler determines both the shielding effectiveness and the cost-efficiency:

• Nickel-Graphite (Ni/C): The most common solution for commercial and military applications. Provides excellent protection against galvanic corrosion on aluminum enclosures.
• Silver-Aluminum (Ag/Al): The Aerospace and Defense standard, offering very high conductivity and low specific gravity.
• Silver-Copper (Ag/Cu): Extremely high shielding effectiveness for applications requiring maximum attenuation.
• Silver-Glass (Ag/G): A lightweight and cost-effective solution for applications where closure force is relatively low.
