TPU is shorthand for thermoplastic polyurethane, and yes, they’re both different and better than butyl in every way, except cost. TPU is lighter, packs smaller, is better rolling, recyclable, more puncture resistant, more cut resistant, and less likey to suddenly deflate than butyl, though they are ~3x the cost of butyl tubes.
