Fluorosilicone Rubber

Fluorosilicones are renowned for their fuel resistance and utility in extreme-temperature service environments. The siloxane backbone results in a polymer with excellent UV, ozone and thermal resistance. The maximum recommended service temperature is in excess of 200 °C (392 °F) for most grades with brittle points as low as -65 °C. Fluorosilicones are used for ‘O’ rings and for wire and cable insulation.

Whilst some adhesive shear strengths are given in Table 4.6 fluorosilicones can often be recommended for high-temperature applications and so if the operating temperature is >100 °C, it is unlikely that cyanoacrylates could be used as suitable adhesives.
