Tough, fatigue-resistant polyimide parts for powersports drivetrains & actuators  

Powersports drivetrain and actuator components face repeated impact, cyclic loading, wear, and installation stress. DuPont™ Vespel® SVT-600 polyimide helps address these challenges with high toughness, good elongation, excellent fatigue resistance, and improved durability in wear-prone components.

Engineered for parts such as secondary clutch rollers, cam followers, and shift actuator elements, Vespel® SVT-600 supports reliable performance in ATVs, UTVs, and snowmobiles – where component failure can increase downtime, increase warranty exposure, and negatively affect customer satisfaction.   

What is Vespel® SVT-600?  

Vespel® SVT-600 material is an unfilled polyimide developed for applications that require toughness, durability, and installation robustness. It offers greater toughness and elongation than Torlon® 4203L and traditional Vespel® grades while maintaining the high temperature performance and dimensional stability for which Vespel® materials are known.  

Why use Vespel® SVT-600 in powersports applications?   

Powersports components often operate under repeated engagement cycles, impact loading, and durability demands. Vespel® SVT-600 helps manufacturers improve component reliability by offering:

• High toughness for improved impact resistance.

• 21% elongation to help withstand installation and operational stresses.  

• Excellent fatigue resistance for cyclic-loading applications.  

• Improved durability in wear-prone components.  

• Reduced risk of brittle failure.  

• Potential warranty claim reduction through longer component life and improved reliability.
