CYG dual wall heat shrink tubing is manufactured from an inner layer of hot melt adhesive and an exterior layer of first-class, soft, cross-linked polyolefin. The exterior wall of the dual wall heat shrink tubing features an outstanding heat insulation, corrosion resistant, and friction resistant performance. The inner layer features a low melting point, an excellent sealing and adhesive performance, and is also waterproof. The dual wall heat shrink tubing is widely used to protect electronic devices against gas and water leaks, and protect cable branches against corrosion, as well as repair cables.
