Combination Yarn Production

Are you searching for a flexible, abrasion-resistant product that provides a tough, high-bond film to go over a conductor?  Our fiberglass polyester combination yarn provides all of these useful features.

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.
