It is expensive enough that you only want to use it when necessary, but they [1] built this place [0] with it. The hot water drill they used to bore into the Antarctic ice cycled between +100 degrees C and -40 degrees C daily, which caused it to develop leaks. This tape is one of the few materials that can survive in those conditions and hold the thing together. Nothing else they tried could do it. [0]: https://icecube.wisc.edu/

However it's not made by 3M, the stuff we have at Pole now is Nitto P-212 [0][1]. It's possible we or other experiments used 3M in the past - given it's been a decade since we broke the ice - but the stuff on station definitely has that blue/white branding on the inside of the roll.
Just to give an idea of how oddly stringent we are down there, and how experimental a lot of this is - regular things break all the time even in relatively controlled environments. Simple solutions like that tape are preferred where possible. The year before I wintered, the IceCube summer crew had to replace over 100 PSU fans in the cluster with equivalent Noctuas because the OEM ones would fail weekly. We did the same with DOM power supplies - I think we use exclusively Meanwell now. Never had any issues with those in my deployment, so it made quite a big difference. It's a harsh continent :)
