Glass yarn (Glass yarn with Water Blocking effect) are primarily used as peripheral strength elements in fibre optic cables. This flexible and flat glass yarn is composed from premium quality glass filaments and PU-polymeric resins to enhance the properties and increase its abrasion resistance to heavy duty processes.
Glass Yarn is one of the very super fine yarn for fiberglass cable filler, textiles fabric, tape for electric, insulation, coating purpose. The glass fiber yarn is formed low fuzz, uniform fiber diameter, stable strength and minimize the weave problem. This yarn is good material used for cables filler for ratproof.
Features
Uniform linear density and low fuzz
High strength
Good electric insulation
High temperature resistance
Application
Fiberglass textiles

Application :
Glass Yarn Armoured Fiber Optic Cable Series are meant for duct applications. Dielectric strength member – Glass Yarn, gives protection to the cable against rodent attacks. Because of their dielectric nature cables can be laid along with high voltage lines inside ducts.
