Ben-Har ST Natural | Heat-Treated Fiberglass Sleeving

Ben-Har ST is a braided, heat treated fiberglass sleeving made of continuous filament E glass. Heat treated fiberglass sleevings were pioneered to provide the fray resistance necessary in most assembly operations. The heat treatment burns off any low temperature contaminants, insures purity and low off gas content and promotes bonding or saturating where desired. Ben-Har ST sleeving is a UL Recognized Component meeting VW-1 flammability requirements. It is completely unsaturated and provides the greatest possible flexibility with the absolute minimum organic content. Its fray resistance makes practical the use of short lengths and the roundness of the sleeving greatly facilitates wire insertion. The special heat treatment of the fiberglass braid prepares the sleeving for bonding with epoxies,impregnates and varnishes resulting in a superior reinforcement between the fiberglass and the encapsulant or varnish. Ben-Har ST is not affected by temperatures up to 240ºC, and can withstand higher temperatures up to the melting point of glass (760ºC.) The sleeving withstands normal assembly handling, cut-through, and mechanical stress without the loss of insulating capability, however performance is determined by wall thickness (about 1/64".) Ben-Har ST shows no effect when exposed to 10 megarads of radiation. It has a nominal outgassing of 0.25% by weight after four hours at 250ºC.
