MULTI-END ROVING
AGY produces conventional or multi-end roving products from S-2 Glass fibers. These roving products are typically used for composite reinforcement applications where high performance fiber reinforcement is required. S-2 Glass Rovings are produced in a variety of constructions, varying by total linear density and by the type of size system applied to the fibers. The products are broken down by the size system and its resin compatibilities. There are 4 families of S-2 Glass Roving products – 365 rovings, 449 rovings, 463 rovings, and 933 rovings. These roving products are described with the size chemistry number followed by the nominal yield in yards per pound.

365 S-2 Glass® Roving
365 S-2 Glass Roving consists of a number of 9 micron or G-filament continuous glass strands, gathered without mechanical twisting into parallel wound rovings with the 365 multi-compatible size system applied.

365 size is compatible with polyester and vinyl ester resin systems, and is suitable for a number of composite processes, including UD pre-preg, filament winding, compression molding, hand lay-up, and weaving.

449 S-2 Glass® Roving
449 S-2 Glass Roving consists of a number of 9 micron or G-filament continuous glass strands, gathered without mechanical twisting into parallel wound rovings with the 449 amino-silane, epoxy-compatible size system applied.

449 size is compatible with amine-cured epoxy resin systems, as well as selected urethanes. The 449 rovings are suitable for a variety of composite processes, including UD pre-preg, filament winding, compression molding, hand lay-up, and weaving.

933 S-2 Glass® Roving
933 S-2 Glass Roving consists of a number of 9 micron or G-filament continuous glass strands, gathered without mechanical twisting into parallel wound rovings with the thermally stable inorganic 933 size system applied.

933 size is compatible with modified epoxy resin systems as well as a variery of thermoplastic resin systems. Specific compatibilities include Polyamide, BMI, Cyanate ester, phenolic, polyimide, PEEK, PEKK, PEI, PAI, and LCP. The 933 rovings are suitable for a variety of composite processes, including UD pre-preg, filament winding, compression molding, hand lay-up, and weaving.
