Filaflex® was developed to operate in applications to withstand continuous temperatures as high as 1400°F (760°C) without flexing or abrasion. Filaflex® is being used in applications to replace asbestos, or where fiberglass won't stand up.
Filaflex® designs contain single conductors insulated with a high strength low alkali magnesia alumina silicate vitreous fiber braid. Prior to impregnation the insulation is inorganic, incombustible and will neither expand or contract with moisture changes. Once the material has been braided onto the wire, it is impregnated with a special binder to improve moisture resistance. The singles are then laid parallel and a braided jacket of the same material is applied and impregnated.
Variations of this construction are available upon request, including protective metal coverings for improved abrasion resistance.
For detailed information on the various thermocouple types, insulation properties, gauge sizes, and wire weights see our Technical Data catalog.
