Introduction of Fiberglass Yarn:

Fiberglass yarns consist of a defined number of E-Glass filaments of a certain nominal diameter, brought together to form a yarn. The structure of the yarn is fixed and protected by a size and a slight twist, generally in Z-direction.

Our E-Glass fiberglass yarns are wound on hard paper/plastic bobbins and supplied in a "milk bottle" shape.The glass yarns can be also supplied on beams. The glass composition meets the certification for E-Glass as defined by ASTM's D578-00 Standard Specification for fiberglass filaments.
