This heat shrink is unsuitable FOR industrial and scientific purposes .It doesn't shrink evenly and leaves gaps, making it inadequate for wiring and connecting. The only positive aspect is that it's heavy wall, but that doesn't outweigh the cons. It`s a waste of money and time..
Pros
Thick and sturdy construction provides excellent insulation and protection.
Cons
Not suitable for small or intricate applications due to its heavy wall thickness.
I made a splint out of this for a broken finger. I simply slipped a cotton glove over my hand, slipped a sleeve over my broken finger and used a heat gun to shrink it down to the right size and shape. Glue the sleeve to the glove. Then I cut off the glove wrap and got a perfectly formed removable guard.
