Excellent resistance to aggressive fuels, oils, and solvents including jet fuels (JP-4, JP-8), aromatic hydrocarbons, and chlorinated solvents.
Retains silicone’s inherent wide service temperature range (–60 °C to +200 °C) with enhanced low-temperature flexibility versus standard fluorocarbon elastomers.
Good compression set resistance after prolonged exposure at elevated temperatures up to 175 °C.
Easy to process via conventional high-temperature vulcanization (HTV) methods including extrusion, calendering, and compression molding.
Meets ASTM D1418 and ISO 1629 classifications for fluorosilicone (FVMQ) elastomers.
Aerospace fuel system seals, gaskets, and diaphragms exposed to aviation turbine fuels and hydraulic fluids.
Automotive under-hood components requiring resistance to engine oils, transmission fluids, and biofuel blends.
Oil & gas downhole elastomeric parts subject to sour gas (H₂S), crude oil, and aromatic-rich media.
Chemical processing equipment seals and linings handling aggressive organic solvents and oxidizing agents.
High-reliability industrial hose covers and expansion joints in dual-fuel or solvent-transfer applications.
