Ben-Har Ex-Flex Heat-Treated End Fray Resistant Sleeving

Ben-Har Ex-Flex is a braided fiberglass sleeving which is heat treated and saturated to prevent end fray and increase ease of handling. This product was developed to meet end fray resistance needs of most assembly operations and for high temperature applications where ordinary film varnish and impregnates cannot be used. Ben- Har Ex-Flex withstands normal assembly handling, cut-through, and mechanical stress without the loss of insulating capability. However, performance is determined by wall thickness. The sleeving is stable in the presence of most organic solvents and shows no effect when exposed to 10 megarads of radiation. Ben-Har Ex-Flex should be considered where assembly conditions or color requirements dictate use of fray retarding or pigment saturant. If subsequent service or accidental temperatures exceed 240ºC, the saturant will gradually volatize without toxic or excessive fumes or smoke. Ben-Har Ex-Flex is used extensively in wire harness assemblies where its flexibility and ease of expansion over irregular terminals and groups of wires makes application easy. It is also used as supplementary insulation on HPN type heater cord leads to protect the primary insulation from mechanical damage and thermal degradation. It will not contaminate delicate terminals or corrode any exposed surfaces. Ex-Flex can be applied in sealed environments, such as steam-dry irons, where the high temperature distillates or ordinary impregnates could damage contacts.
