Water Blocking Yarn

Water Blocking Yarn

This yarn has good heat-resistance property. It is non-corrosive and has no acid or alkali included.  With its fast water absorbing speed and high tensile strength, the Star Materials Water blocking yarn is used in communication cables, optical cables, power cables or marine cables for the purpose of binding, tightening and to prevent water penetration.
