Binder Yarn

SUNPURE's Binder Yarn is a Low Shrinkage Polyester Binder yarn coated with non-wicking material, hence preventing capillary effect. SUNPURE WS is Water Swellable version of binder yarn used to prevent water penetration in the cable. Both are applied contra-helically with sufficient tension to secure each buffer tube layer to the central member without crushing the buffer tube. However, SUNPURE WS offers added protection against water penetration in the cable.

  • Binder yarn with non-wicking properties.
  • Cost-effective water swellable product especially for dry cables.
  • Precisely wound packages with variety of packaging options.
  • Available in various colours for identification purpose.
  • Environment friendly products.
