Approved by GENERAL MOTORS, the TENSODIEL (heat shrink) - EM 1329 tape is made up of a combined weave of chain polyester thread and glass weft thread, which allows for significant contraction under the influence of temperature. This fabric is impregnated with a highly flexible modified epoxy system. It enhances compactness in coil heads of rotating machines as its primary application. It is also used in insulating connections and various joints.
