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.
SUNPURE is manufactured using low shrinkage continuous polyester filament yarn of different denier/dtex and is coated with anti wicking material.
SUNPURE WS, is manufactured by applying SAP coating on binder yarn for imparting water swellable properties. Both Binder Yarns are available in various colours for identification purpose. Binder yarns of long continues lengths are supplied in a variety of packages.
