Aircraft Engine Fan Components


DuPont performance resins provide wear resistance and low friction under high stress in aircraft engine fans 

For over 50 years, DuPont resins have helped propel aircraft fan technology.

DuPont™ Vespel® is a proven performer for:

• Fan blade wear strips
• Abradable seals
• Blade spacers

In addition to providing strength, wear resistance, and low friction under high loads, Vespel® is an excellent choice for low-weight, low-cost seals. 

When used for fan blade root wear strips, Vespel® reduces blade stress and protects them from wear and corrosion. Vespel® wear strips also provide controlled, predictable, and consistent friction for blade seating.

Vespel® abradable seals with zero clearance improve fan and compressor efficiency and cost less than typical honeycomb structures.
