Will shrink tubing damage a painted surface over time? Or would it preserve it? Just curious? & would it be easy to remove? Or does it have Adhesive on the inside?
Hi Paul Maldonado, Thanks for your questions. It depends on many factors. The shrink tubing itself will not damage the surface. But it depends on the type of paint and the surface itself. In any case, the heat shrink is a protection against external influences. "How can you remove heat shrink tubing?" You can learn how to remove heat shrink tubing here: th-cam.com/video/AguKB6z606M/w-d-xo.html We offer a wide range of heat shrink tubing, with and without adhesive: check out this page: www.hellermanntyton.com/competences/heat-shrink-tubing?TH-cam-description&FAQ-2019-nr1-TXVDttykxIA-en-heat-shrink-tubing I hope I could answer your questions, otherwise contact us again, Nico
Hello Dj Skaghead, you are correct from a physical perspective that substances expand when heated. However, in this case, we are dealing with extrusion. This means that the tubings are stretched, and through another processing procedure, the tubing remains in the stretched state until it is heated. At that point, it wants to return to its original form. Marc explains this quite well here: th-cam.com/video/TXVDttykxIA/w-d-xo.html Best wishes, Nico
Hi xderiwx, Heat Shrink Tubing does not only shrink in diameter when heated but also minimal in length. The so called “longitudinal shrinkage” of the “TREDUX” Heat Shrink Tubing shown in this video is 5% max. Best wishes, Nico
Hi chris ross, Mark is mentioning it: th-cam.com/video/TXVDttykxIA/w-d-xo.html. It's extruded. A starting tube will be extruded from the raw material. The tube is then taken to a separate process where it is cross-linked, usually by radiation. The cross-linking creates a memory in the tube . The tube is then heated to just above the crystalline melting point of the polymer and its diameter is expanded. In the expanded state, the tube is cooled down rapidly. Later, when the tube is heated, the tube shrinks back to its original extruded size. Best wishes, Nico
What people who would have found this video really want to know is, how is the tubing expanded in the first place? What is the process by which this is done?
"Heat shrink tubing is extruded plastic tube that is expanded and will shrink back to its extruded size when heated. Heat shrink is used to electrically insulate cables and wires offering also mechanical and chemical protection." --> Extruding
What size do I need to cover an object 12mm to 16 mm in diameter?

Heat makes substances expand. So how does it so the complete opposite in this case??!

Does the tubing shrink down in diameter only, or also length?

Technically it does but not by any noticeable amount.
How is heat shrink tubing made?
