Advantages and Disadvantages of FKM Rubber
Advantages: Resistant to extreme high temperatures and strong corrosion; Broadest range of media resistance; Excellent air tightness; Long service life (5~10 years in harsh environments).
Disadvantages: Extremely high cost (5-10 times that of NBR); poor low-temperature elasticity (easily brittle at -20℃); complex processing technology and difficult molding.
Typical Applications:
Aerospace: Engine fuel lines, hydraulic system oil lines, high-temperature steam delivery lines (ground testing of aerospace equipment).
Petrochemical: High-corrosion media delivery lines (e.g., strong acids, strong alkalis, organic solvents), high-temperature reactor unloading lines, chemical pump sealing sleeves.
High-end Automotive: High-temperature oil lines for turbocharger systems, engine exhaust system sealing lines, new energy vehicle battery cooling lines (high-temperature conditions).
Special Equipment: Fluid lines for semiconductor manufacturing equipment, hot air delivery lines for high-temperature ovens, strong solvent delivery lines in the pharmaceutical industry.
