Our fiberglass polyester combination yarn is exactly what the name says – one end of continuous filament fiberglass yarn twisted together with polyester continuous filament yarn (thermal class B). The resulting product often serves as an overwrap for steel, aluminum and copper conductors, with the overwrap heated and fused to provide electrical and oxygen isolation of the conductor. We offer fiberglass polyester combination yarn as multiple ends wound on serving packages.
