Heat shrink plastics will shrink in 1 or 2 dimensions, but expand in the 3rd (thickness). When the plastic shrivels it's getting shorter, but it also gets thicker. In summary, some plastics seem to shrink when heat is applied, due to the negative thermal expansion (nte) phenomenon. Each plastic material has a distinct.
