Heat shrink means just that—when heat is applied to the sleeve, it shrinks in size and conforms to the surface it surrounds. A heat-shrink sleeve starts out with a thick extruded polyolefin sheet (polyethylene or polypropylene) that is formulated to be cross-linkable.

Heat-shrink sleeves have an adhesive that sticks the sleeve to the material and the factory-applied mainline coating, and also acts as a corrosion protective layer.
