What happens to singly-ply thermoplastic membranes when exposed to heat?

Explanation:
Singly-ply thermoplastic membranes respond to heat by softening. The heat increases the mobility of the polymer chains, making the surface pliable so sheets can flow slightly and be welded together into a watertight seam. This softening behavior is what allows heat-welded seams to form strong bonds. They don’t harden with heat, and cracking or shrinking aren’t the typical responses unless the material is overheated or damaged, respectively. So, the best description is that they soften when heated.
