Heat Shrink Sleeves are manufactured from radiation-crosslinked polyethylene tape, provided with a self-priming thixotropic sealant. The total thickness is 1.5 - 2.5 mm, with a backing tape of 0.6 - 1.0 mm. Heat shrink sleeves provide a safe and efficient method for protecting fusion splices on either 250 or 900 micron coated fibers. Heat shrink sleeves are threaded on to fibers prior to fusion splicing and then positioned directly over splice & heated via an oven or heat gun. Heat shrink sleeves are labels that are applied to a container and shrunk to fit the contours of the container through the addition of heat.

Heat Shrink Tubings are used for product and manufacturing applications including electrical insulation, mechanical reinforcement, encapsulation, marking and identification. The heat shrink tubings are pressed against cylindrical metal rods for shaping while being heated. Heat shrink tubings made of special-purpose plastics serve both as electrical insulation and as protection against corrosion. These tubings are suitable for covering condenser, wire, battery, pole, medical instrument to serve the purpose of insulation and consolidation of products.
