SI60BK15 Datasheet

SI60BK15 is a 60 shore A black conductive silicone compound from CanGuard designed for electrostatic discharge control and EMI shielding applications. This carbon-filled silicone provides reliable ESD performance and low frequency shielding, making it ideal for O-rings and gaskets used in electronics enclosures, connectors, and shielding interfaces. It maintains flexibility across a service temperature range of -55°C to 160°C, with stability through short temperature excursions, and is tested to MIL-DTL-83528 standards. While it performs well electrically, SI60BK15 has limitations including lower abrasion resistance and potential corrosion in salt mist environments, which should be considered during material selection.

 

Conductive silicone (VMQ) materials are widely used in specialized O-rings and gaskets where electrical conductivity or EMI shielding is required alongside environmental sealing. These compounds incorporate conductive fillers such as carbon to provide controlled resistivity while maintaining the inherent flexibility and temperature range of silicone rubber. They are commonly used in aerospace, telecommunications, and electronics industries where protection against electrostatic discharge and electromagnetic interference is critical. Compared to standard silicone, conductive grades trade some mechanical durability for electrical performance, making proper application design essential.
