Application:
- Aerospace industry: used in aircraft as seals to resist fuels and/or lubricants, such as O-rings, spacers, integral tank sealing, seal rings, sensor materials, diaphragms and clips for fluorosilicone spacers.
- Automobile industry: used as sealing rings, grease seal, diaphragms, pipes and valve-linings for various types of vehicles.
- Petrochemical industry: sealing elements used in pump, valve and oil tank, which are used in high/low temperature and chemical circumstance.
- Medical and health care: used in manufacturing medical apparatus or instruments, and artificial visceral organs, such as medical pipes, medical hoses for fluids and artificial valves.
- Martial industry: used in poor environment, which requires materials to resist low temperature, oil and acid, for instance, corrugated pipes used in hydraulic system of martial aircraft, sealing rods for doors, windows and covers on special vehicles, sensor materials and etc.
