.... The plastics that tend to do this are termed crystalline plastics; the ones that do not are amorphous, and there is an in-between called semicrystalline. Polyethylenes tend to be crystalline; polystyrenes tend to be amorphous. Molecule size also matters. A classic example is polystyrene. Many commodity...
