KHA3-H extra thick, heavy-duty heat shrink tubing for more high-intensity environments, with thicker walls, adhesive linings and a variety of sizes, KHA3-H Weather proof heavy wall heat shrink tube are ideal for insulating and protecting cable joints and terminations, and can also be used for repairing cables.
What is adhesive lined heat Shrink Tubing?
Heat Shrink Tubing, also called heat shrinkable tubing, is a tube shrinking to smaller when heated. When heat is applied to the heat shrink tubing, the adhesive material inside of the tube will melt. The adhesive material secures it to the wire or cable. The process allows the wire or cable and the heat shrink tubing to become one unified product.
How to use a heat gun to shrink the tubes?
When you use a heat gun to shrink the tubing, you need to keep the heat gun moving back and forth along the length of tubing, as staying in one place can damage the wire even further, continue heating the tubing until it is tightly secured to the wire.
Why does heat shrink tubing shrink?
There is a technical treatment named cross linking, the process of cross-linking is exposing a polymer to radiation in order to create covalent bonds between that polymer's atoms. it was discovered that radiation was capable of altering the molecular structure of certain plastics so that they wouldn't melt or develop a flowing consistency, no matter what temperatures they were exposed to. Covalent bonds also give polymers plastic memory, which means that once a polymer has been cross-linked and stretched into an expanded shape, it will automatically shrink back to its original dimensions when a certain amount of heat is applied.
