Features Of Dow SILASTIC LS 5-8760 Fluorosilicone Rubber Base

  1. Exceptional resistance to fuels, lubricants, and aggressive hydrocarbon-based fluids across wide temperature ranges.

  2. Outstanding low-temperature flexibility down to –60 °C, maintaining elastomeric performance in extreme cold environments.

  3. Enhanced thermal stability with continuous service capability up to 200 °C.

  4. Low compression set for reliable long-term sealing integrity under dynamic and static conditions.

  5. Compatible with standard platinum-cure silicone processing equipment and techniques.

Typical Applications Of Dow SILASTIC LS 5-8760 Fluorosilicone Rubber Base

  1. Aerospace fuel system seals and gaskets exposed to jet fuels and synthetic lubricants.

  2. Automotive turbocharger hose couplings and sensor seals operating in high-heat, chemically aggressive under-hood environments.

  3. Oil & gas downhole instrumentation seals requiring resistance to sour gas (H₂S), crude oil, and drilling fluids.

  4. Industrial fluid handling components such as diaphragms, valve seats, and pump liners in chemical processing plants.

  5. Medical device tubing and connectors where biocompatibility is not required but chemical inertness and sterilization resistance are critical.
