Vectran® (LCP): Strength & Flex Fatigue

Key Features of Vectran® LCP:

  • High strength to weight ratio
  • Good creep resistance
  • High abrasion resistance
  • Good flex fatigue properties
  • Minimal moisture absorption
  • Excellent chemical resistance


History
First produced in 1990, Vectran® is the only commercially available melt spun LCP fiber in the world.  

Composition
Vectran® is an aromatic polyester spun from a liquid crystal polymer in a melt extrusion process.  This process orients the molecules along the fiber axis, resulting in a high tenacity fiber.
