-75°F (-59°C) to 400°F (204°C)
Hardness (Shore A) Range:

Also Known As:
Silastic LS®, FSE®
Fluorosilicones are used widely in jet fuel applications and where the dry-heat resistance of silicone is required.
Excellent resistance to petroleum oils and hydrocarbon fuels as well as diester base lubricants (up to 175°C).
Compared to silicone, it has a poor hot air resistance, and poor physical characteristics restricting its use with dynamic applications.
