Heat shrinkable plastics are one of the most important and continually intriguing results of research involving the crosslinking of polymer molecules. As the name implies, these are products -- supplied oversized for use -- which recover rapidly to predesigned dimensions when heated above a given temperature. They “remember” their shape and return to it. The purpose of the paper is to describe a wholly unique class of coating materials which are based on this shape memory property. The most familiar example is the heat shrinkable sleeve for welded and coupled pipe joints, widely accepted today in the oil and gas industries (Figure 1). Extruded and molded heat shrinkable plastics such as the “pipe sleeve” represent a significant advance in protective coatings technology for corrosion control.
