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.
