Fluorosilicone Rubber is a specialized elastomer that combines the properties of silicone rubber and fluorocarbon rubber. It is known for its exceptional resistance to fuels, oils, solvents, and extreme temperatures, making it suitable for demanding applications in aerospace, automotive, and industrial sectors.
Features
- Exceptional chemical resistance (fuels, oils, solvents, acids).
- Wide temperature range (-60°C to 200°C).
- Fuel and oil resistance (jet fuels, diesel, gasoline, hydraulic fluids).
- Weather and ozone resistance (UV, ozone, weathering).
- Good compression set resistance.
- Flame resistance (inherently flame-retardant).
- Low gas permeability.
Applications
- Aerospace: Fuel system seals, O-rings, hydraulic components.
- Automotive: Fuel injector seals, valve stem seals, engine gaskets.
- Oil and Gas: Downhole seals, refinery gaskets, chemical-resistant parts.
- Industrial: Chemical processing seals, machinery components.
- Electrical: Harsh environment seals, insulators.
- Medical/Food: Biocompatible seals, food-contact gaskets.
- Military: Fuel system seals, engine components.
