Waterblocking Yarn

Waterblocking Glass Yarn

Waterblocking Glass Yarns is a kind specialized yarns with good water absorption capacity, mainly used for moisture control and reinforcement in coating protection of Cable, optical Cable, communication Cable or fiber optic Cable.

Composition

Polyester Terylene long fiber

Polyacrylate super-absorbent resin

Advantages:

Optimize cable structure, replace jelly for water blocking

Relative humidity inside the cable is kept below critical levels

Prolonged cable life due to slower or zero water tree growth

Life spans over than 30 years with the proper materials

No need for a metal (radial) water barrier.

Less environment impact

More reliable and cleaner cable production.

Lower investment in manufacturing equipment.

To avoid extrusion from finished cable/plastic mold on optical fiber bundle tube, and reduce defective rate

H.S.CODE: 7019120090 & weight 9-10 tons for 20 FCL
