Glass Yarn

Yarns

Application

Glass yarn is a new type of non-metallic core strength component. It has been widely used in optical fiber cables.It’s a strength member between cable jacket and cable core.There are two types: glass yarn and water blocking glass yarn.

Features

Two types:
1.coated glass yarn, non-water blocking
2.water blocking glass yarn, excellent swelling properties
PU coated, good tenacity, not easily broken off and no dermal harzardous to people while processing.
