THERMOFLUX MULTICOLOUR is a flexible, heat shrinkable tubing with an integrally bonded meltable adhesive inner lining, designed to provide permanent moisture proof encapsulation to a wide variety of substrates and uses; such as electrical wires, cable jackets, wire breakouts and electrical components. It has has a unique inner wall, which melts when heated and is forced into the crevices and penetrates by the shrinking action of the outer wall. When cooled the entire mass becomes a fl exible, tough homogeneous covering with a controlled wall thickness. This product is manufractured from radiation cross-linked polyolefins. It has a specially formulated adhesive inner wall. THERMOFLUX MULTICOLOUR shrinks to 1/4 of its supplied diameter and thus only three sizes are required to cover a full range of irregular shapes with widely varying applications.
