I have noticed a lot of electronics use kapton tape in places where a heat resistant tape isn't necessary. Why is that so? Is it just because it's a good adhesive?
If you go through all the trouble to test and qualify something, like tape: check it doesn't unstick after a few years leaving glue everywhere, doesn't shrink or loosen or harden or crack, even if the product is left in a car baked in full sunlight for months... then you probably won't feel like re-doing that work for another tape, especially if it saves no money and using a new tape brings new risks of failure for your product.
If you repair old equipment, you'll notice the kapton tapes always look like they're new, but the other types, not so much. PVC "electric tape" is one of the worst.
So basically, if it aint broken, dont fix it.
