What Is Silicone Cord Used For?

Silicone cord is a flexible, high-performance sealing and insulation material made by extruding solid silicone rubber into long, continuous cylindrical lengths. Known for its excellent temperature resistance, durability and inert chemical properties, silicone cord is widely used across industries where reliable sealing or cushioning is required.

Common Applications for Silicone Cord Include:

  • Seals and Gaskets: Ideal for creating custom O-rings or perimeter seals in enclosures, ovens, or industrial equipment.
  • Food and Beverage Equipment: Food-grade silicone cord is safe for contact with consumables and used in processing machinery.
  • Pharmaceutical and Medical Devices: Offers excellent hygiene and chemical resistance for use in sterile environments.
  • Electrical Insulation: Used in cable assemblies or to insulate sensitive electrical components from heat and moisture.
  • Automotive and Aerospace: Suitable for high-temperature sealing and vibration dampening in engines and airframes.
