CONTINUOUS FILAMENT YARNS
AGY produces S-2 Glass® Yarns, which are continuous fibers twisted together to provide strand integrity and processing advantages for textile processes such as weaving, braiding, plying, and cabling. S-2 Glass Yarns are available in a number of constructions and size systems tailored to meet the needs of the end user. There are two main families of S-2 Glass Yarns – starch oil sized yarns and direct sized yarns.

S-2 Glass® Yarns – Starch Oil Size
AGY produces D450, G150, and G75 yarns with a starch/oil size system optimized for weaving processes where fabrics will be heat cleaned and finished with fabric finishes. These yarns consist of numerous filaments twisted together to form single yarns. The size chemistry protects the glass filaments from abrasion during processing and is typically removed after processing. Fabrics are treated with resin-compatible finishes.

S-2 Glass® Yarns – Direct Size
AGY produces G150 and G75 yarns with direct size systems that are optimized for resin-compatibility without fabric heat cleaning and finishing requirements. These yarns are developed for typical yarn processes such as weaving, and are developed with direct size systems to provide added value to the composite manufacturers.

Size systems
493 – compatible with epoxy and polyester resins
933 – compatible with modified epoxy resins and a variety of thermoplastic resins systems.
762 – compatible with RFL and choloprene rubber
