LAYERS
18, 19 Du Pont announced "Kapton" in 1964. Two aluminized layers protect the astronaut from extremes in temperatures, 330 degrees F. in moon day to minus 250 degrees F. in moon night. "Kapton" was chosen because it will not shrink, melt, or burn at high temperatures, even when as thin as one-thousandth of an inch. It was also used in the moon landing space ship to insulate 14 miles of wire. On earth, "Kapton" is used to insulate motors for high-speed trains and wiring for aircraft. Taken from a 1970s DuPont poster. |
