Used to motivate electron-beam cross-linking as a general manufacturing technology, before applying it to PEX-A.

Why do you need to go to electron beams to cross-link? It turns out they do the same thing when they're making sandpaper. Sandpaper is this paper, and they put some glue on it and put some sand on that, and they want to glue the sand to the paper. There's no adhesive that sets up fast enough when they're running this paper through the machine at about fifty miles an hour. It'll still be wet by the time you want to coil it.
