Performance failures are not an option in aerospace and defense. Every component must endure harsh extremes: temperature swings, high altitudes, pressure variations, and constant vibration. PTFE is uniquely suited for these environments, delivering thermal stability, chemical resistance, and electrical insulation in a lightweight material.
PTFE is widely used in fuel systems, wire insulation, hydraulic sealing, and structural components in commercial aircraft and military hardware. Its low coefficient of friction makes it ideal for bearing surfaces and bushings, while its nonflammable and non-reactive properties make it suitable for electronics and control systems.
PTFE’s value in aerospace lies not only in performance but also in weight reduction. As every ounce counts in flight, PTFE offers a reliable, lightweight alternative to metal and other traditional materials.
- Lightweight Strength: Combines low weight with high durability, making it ideal for precision components
- Nonflammable & Thermally Stable: Maintains stability and resists ignition under extreme temperatures.
- Low Outgassing: Engineered for vacuum environments, PTFE emits minimal volatiles, perfect for space applications.
- Electrical & Chemical Resistance: Offers excellent electrical insulation and resists chemical reactions in harsh conditions.
- Aircraft Electrical Insulation: PTFE is an excellent electrical insulator, and it is used in the aerospace industry to insulate wires, cables, and connectors. It can withstand high voltages and extreme temperature variations.
