water blocking yarn for optical fiber cable
Product description
In the production of cables by using water blocking yarn,the materials of water blocking tape,polyster yarn and ointment could be omitted.Besides that,water blocking yar is convenient in using,simple in techniques,stable in structure,reliable in water blocking,clean in environment,and no greasy pollution,especially,used in waterproof communication cable,dry-type cable,and insulation electronic cable,especially benthic cables.etc.
Characteristics
1.Quick water absorption,high expansivity,high tensile strength
2.Heat resistance,chemical stability and corrosion resistance
Application
Used for water blocking between components of communication cable and optical cable
