When you need a lower heat shrink temperature than PVC heat shrink tubing, as well as the ability to work in confined spaces, then Ultra-Thin Wall and Low Shrink Temperature heat shrink tubing are right for you.
Both have a lower shrink temperature and higher operating temperature than PVC and shrink to half their original diameter. Low Temperature shrinks at only 80°C (176°F) and Ultra-Thin Wall shrinks at 100°C (212°F). Both have an operating temperature of -55°C to 125°C (-67°F to 257°F).
Low Temperature is available in black and clear. Ultra-Thin Wall comes in black only.
A: No. In fact, they're designed for when you don't need extra protection from heat, chemicals, abrasives, or other harsh environments. This heat-shrink tubing is generally for lighter-duty uses, such as insulation, wire identification, wire bundling, mechanical protection, lightweight harnessing, physical/electrical protection of components, strain relief, and solder insulation.
A: Yes, because it still shrinks at a 2:1 ratio, meaning that it will still create the same tight hold as much thicker heat-shrink tubing in the same ratio. The advantage is that it won't be as thick on the outside, so won't take up as much room in your wiring job.
