3M is a manufacturer of this recent type of shrink tubing. The inner
material is a glue that melts when it's heated. The glue fills the voids and
also makes if impossible for the heatshrink to slip. Almost invariably older
heatshrink will be damaged by years of UV and actually expand enough for the
tubing to slide off the joint. The new stuff is thicker and solves these
problems. It IS expensive - a buck an inch or more.
I have found that the heatshrink will peel right off after being sliced
open with a razor knife.
