China Factory Price 68 Tex Glass Fiber Fiberglass Roving Yarn G75
The single fiber diameter of electronic-grade E-glass fiberglass yarn is mainly 5-9 microns. The surface of the yarn is coated with a special starch sizing agent, which has a good protective effect on glass fiber bundles, and has less hairiness during decomposing and weaving, excellent textile performance, and finished yarn. After weaving, the sizing agent is easy to de-sizing, the decomposition temperature is low, the final ash residue is low, and the fabric is white and smooth after de-sizing. Electronic grade fiberglass yarn is the basic material used to produce electrical insulating glass fiber series products, and is an indispensable and irreplaceable high-quality structural material for copper clad laminates and printed circuit boards.
