Glass Filament Yarn is treated with a starch-oil based size which improves subsequent handling and fabrication operations.
Glass Filament Yarn is mainly used to produce PCB cloth which is the basis material for various information processing eqiopment and widely used for making the core plates of computers and telephone sets, communication apparatus and home appliances.

Glass filament Yarn is mode by twisting and/or plying a number of fibre glass strands. The number and diameter of fibers thet are twisted and plied together affect the strength, diameter and flexibility, of the yarn.

Product features
Consistent strand linear density. Low twist which contributes to the dimensional stability of circuit boards. Splice free, defect free and low fuzz. Starch-based size easy for themal cleaning. Good copatibility with resins and high strength. Good elestrical insulation property.

Packaging:
Glass filament yarn is wound onto a plastic tube, The weight of a full package is over 3kg. The packages are packed on a pallet. In order to maintain loading stability and prevent moisture, shrink wrapping is used
