EMI & RFI Shielding Materials

Conductive elastomers are silicone or fluorosilicone bases loaded with fine metal particles to create a flexible, conductive path. Common fillers include silver-aluminum, silver-copper, nickel-graphite, silver-glass, and pure silver, each selected for specific conductivity and corrosion resistance requirements. For environments exposed to fuel, oil, or solvents, fluorosilicone-based conductive compounds are preferred. Canyon Components also provides conductive thermoplastics and fabric-reinforced gaskets for lightweight applications. Every compound is engineered to achieve a balance between electrical conductivity, mechanical resilience, and environmental sealing, ensuring that the gasket or O-ring performs reliably even under vibration, temperature cycling, and humidity. If you have any questions or require design assistance, feel free to reach out to the Canyon Components engineering team!

The CanGuard series is designed to deliver consistent performance across a wide range of environmental and electromagnetic conditions. Each formulation undergoes testing for volume resistivity, shielding effectiveness, compression set, and environmental exposure to verify long-term stability. CanGuard materials maintain their conductive properties even after repeated compression cycles, minimizing contact resistance between mating surfaces. Canyon Components also tailors compound formulations to meet MIL-DTL-83528, ASTM, & SAE AMS specifications, ensuring compatibility with aerospace and defense requirements. Beyond standard sizes, we offer custom extrusions, molded shapes, and overmolded components, providing complete integration between EMI protection and mechanical sealing. If you have any questions or require design assistance, feel free to reach out to the Canyon Components engineering team!

Conductive silicone is ideal for general-purpose EMI and RFI shielding in enclosures and housings that are not exposed to harsh fluids. It provides excellent flexibility, temperature resistance, and low compression set. Conductive fluorosilicone, on the other hand, is formulated for environments where fuels, hydraulic fluids, and solvents are present, such as aircraft, defense systems, and industrial electronics. Canyon Components supplies both materials with a range of conductive fillers that achieve surface resistivities as low as 0.004 ohm-cm. Our engineers help customers determine whether the chemical compatibility of fluorosilicone or the broader temperature tolerance of silicone best suits the intended environment. If you have any questions or require design assistance, feel free to reach out to the Canyon Components engineering team!

Shielding gaskets are tested for shielding effectiveness in decibels (dB), measuring their ability to attenuate electromagnetic signals across specific frequency ranges. Tests often follow methods such as MIL-DTL-83528 depending on the application. Canyon Components evaluates CanGuard products for both electrical conductivity and mechanical endurance, ensuring the gasket maintains its contact resistance and sealing properties after compression, vibration, and temperature exposure. We also perform salt fog, humidity, and corrosion testing to confirm that conductive fillers remain stable and that the gasket continues to meet required performance standards over extended service life. If you have any questions or require design assistance, feel free to reach out to the Canyon Components engineering team!

Yes. Many modern applications require seals that provide both EMI/RFI protection and traditional environmental sealing against water, dust, or gas. Canyon Components produces hybrid gaskets and O-rings that combine conductive paths with non-conductive elastomers, achieving both electrical shielding and IP-rated environmental protection. These hybrid seals are ideal for connectors, housings, or bulkheads that must meet both EMC and ingress protection (IP) standards. We can mold conductive and insulating sections into a single component or bond them mechanically to provide seamless integration between electrical and mechanical sealing functions. If you have any questions or require design assistance, feel free to reach out to the Canyon Components engineering team!

Yes. Many CanGuard compounds are designed to meet the performance expectations of MIL-DTL-83528, SAE AMS specifications, and NASA outgassing standards. These materials are commonly used in avionics housings, radar systems, satellite communications, and military electronics where EMI suppression is critical to mission safety and communication clarity. Canyon Components also provides documentation for material traceability, batch testing, and compliance with RoHS and REACH directives. For aerospace customers, our team can assist with design optimization to minimize weight while maximizing shielding performance and vibration resistance in extreme temperature or altitude environments. If you have any questions or require design assistance, feel free to reach out to the Canyon Components engineering team!

Integration depends on the geometry and operating environment of the equipment. Conductive gaskets are typically installed between conductive metal surfaces, allowing them to bridge the gap and form an electrical seal. Canyon Components offers custom die-cut, molded, and extruded profiles that match complex housing designs, from thin flange interfaces to large rectangular enclosures. For high-frequency shielding, we provide knitted wire mesh and fabric-over-foam solutions that conform to uneven surfaces without compromising contact continuity. Our engineers collaborate with design teams to ensure proper compression force, contact area, and surface finish, which are all vital to achieving consistent EMI and RFI protection. If you have any questions or require design assistance, feel free to reach out to the Canyon Components engineering team!

Absolutely. Every application has unique geometry, frequency exposure, and environmental requirements. Canyon Components specializes in custom-molded conductive O-rings, frame gaskets, connector seals, and integrated assemblies that meet precise design tolerances. We use CAD modeling and precision tooling to replicate or improve existing designs, producing components that offer both mechanical durability and electromagnetic integrity. Our rapid prototyping services allow customers to evaluate performance before committing to full-scale production, ensuring optimal fit and shielding efficiency. If you have any questions or require design assistance, feel free to reach out to the Canyon Components engineering team!
