Canyon’s FS75BU51 is a 75 Shore A blue CanGuard Fluorosilicone compound engineered specifically for EMI and RFI shielding applications where environmental sealing and electrical conductivity are both required. Filled with silver plated aluminum and manufactured to MIL-DTL-83528 Type D, it provides effective electromagnetic shielding while maintaining good flexibility and compression set resistance. With a service temperature range of -55°C to 160°C (-67°F to 320°F), FS75BU51 performs reliably across wide thermal conditions while resisting fuels, oils, aging, weathering, and ultraviolet exposure. Its fluorosilicone base chemistry supports use in fuel-rich and chemically aggressive environments where standard conductive silicones may degrade.
FS75BU51 is commonly used for conductive O-rings, gaskets, and sealing elements in aerospace, defense, electronics enclosures, and shielded connectors where EMI and RFI control is critical. The combination of conductive filler and elastomeric sealing performance makes it suitable for applications requiring both environmental protection and electromagnetic compatibility. This compound offers a balanced solution for designers seeking MIL-qualified shielding materials with fuel resistance and long-term durability.
