Ben-Har ST is a braided, heat treated fiberglass sleeving made of continuous filament E glass. 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 sleeving is completely unsaturated and provides the greatest possible flexibility with the absolute minimum organic content.
