Spectra and Vectran line have extremely low stretch and are perfect for performance applications such as travelers or as part on a control set up.
If you're looking for line with near zero stretch, then our selection of Dyneema, Spectra, and Vectran lines are for you! These high tech lines have near zero stretch and perfect for performance applications such as travelers or as part on a control set up. These lines are uncovered and more likely to wear, but do feature UV coating to protect from sun damage.
Dynema® and Spectra® are made from UHMWPE (Ultra High Molecular Weight PolyEthylene), a long chain, high strength, oriented strand, synthetic fiber with very high strength and high abrasion resistance. This fiber is also known as HMPE (High Modulus PolyEthylene). Dynema® is the Dutch company DSM Dyneema's brand of UHMWPE, used by Samson in their Amsteel and Amsteel-Blue dyneema lines. Honeywell International produces a similar UHMWPE fiber, marketed as Spectra®. Both Dyneema (Dynema) and Spectra offer nearly identical characteristics are can be used interchangeably in sailing applications, depending on where you source your line.
Made from a LCP (liquid crystal polymer) fiber, Vectran exhibits high strength, excellent creep and abrasion resistance, excellent flex/fold and chemical resistance, and outstanding heat and cut resistance. Vectran is an alternative to Dyneema or Spectra and less stretch and creep. Many think Vectran is the ultimate fiber, though it does not have quite the fatigue life or UV resistance of Dyneema or Spectra. Also it is a little heavier and will not float.
