SUMITUBE™
SUMITUBE is a heat-shrinkable tube (that shrinks in the radial direction when heated) that takes advantage of the shape-memory effect of plastics enhanced by electron beam irradiation. Made mainly from raw materials such as polyolefin, fluorinated polymer, or thermoplastic elastomer, SUMITUBE is widely used in various industrial fields for bundling, thermal protection, and insulation protection of electrical wires and harnesses, as well as for other purposes.
