Polyethylene was invented in the early 1930s and played an important role for the Allied Forces in World War II. British scientists took polyethylene and used it as an insulator allowing British pilots to have radar on their planes for the first time in history. Airborne radar was a great technical advantage for battles fought through clouds with low visibility and for long-distance warfare. Polyethylene has come a long way, as it is now cross-linked and used for plumbing and heating water lines all throughout Europe and North America.
