I. Material Properties Analysis
Fluorosilicone rubber (FVMQ) is a specialty synthetic rubber whose fluorine atoms incorporated into its molecular chain impart unique properties:
Chemical Stability: With a C-F bond energy of up to 485 kJ/mol, it resists swelling and corrosion from hydrocarbons such as aviation fuel, hydraulic oil, and lubricating oil.
Temperature Adaptability: It maintains elasticity within a temperature range of -50°C to 200°C, surpassing ordinary silicone rubber (with an upper temperature limit of 150°C).
Physical Properties: Typical hardness ranges from 50-80 Shore A, tensile strength from 5-10 MPa, and elongation from 150-400%.

II. Typical Applications
Aerospace: Fuel system seals, hydraulic pipe fittings, and O-rings.
Automotive: Turbocharger intake manifolds and transmission oil seals.
Energy: Offshore drilling platform blowout preventer seals and pipeline valve gaskets.
