Vectran™ at high temperature
Mechanical property retention during or after thermal exposure is a key concern in many applications. The tensile strength of Vectran™ at temperature should be used as a reference in selecting process conditions.
Vectran™ after thermal exposure
For high-temperature processing at low mechanical load, Vectran™ will have excellent strength after processing, superior to aramids.
Vectran™ resistance to cyclic thermal loads
The resistance of Vectran™ to cyclic thermal loads at higher temperatures is superior to aramids and increases product lifetimes.
