The Advantages of PTFE in Aerospace Applications

1. Unmatched Chemical Resistance

• Resistant to a wide range of chemicals and solvents, including jet fuels, hydraulic fluids, and lubricants
• Extends the service life of components and reduces maintenance costs

2. Exceptional Temperature Resistance

• Withstands extreme temperatures, ranging from -328°F to 500°F (-200°C to 260°C)
• Ensures reliable performance in harsh environmental conditions, both in-flight and on the ground

3. High Electrical Insulation

• Excellent dielectric properties, making it ideal for use in electrical insulation and wiring applications
• Helps prevent electrical shorts, arcing, and other potential hazards in aerospace systems

4. Low Coefficient of Friction

• Minimizes friction between moving parts, reducing wear and extending component life
• Eliminates the need for additional lubricants, simplifying maintenance and reducing potential sources of contamination

5. Excellent Weather Resistance

• Resistant to UV radiation, moisture, and other environmental factors
• Maintains performance and durability in challenging weather conditions

6. Lightweight and Durable

• Offers strength and durability without adding significant weight to aerospace components
• Contributes to overall weight reduction, improving fuel efficiency and aircraft performance
