NASA first used DuPont™ Krytox® performance lubricants for the Apollo space flights in the 1960s. These days, they are also used here on Earth for everything from bicycle chains to the spark plugs in NASCAR champion Jeff Gordon’s car.

Krytox® oils and greases work at high and low temperature extremes to keep engine parts running. They are nonflammable, chemically inert and safe to use in all areas of oxygen service. That makes them work well whether traveling on land or through outer space.

Among other DuPont products that have gone up in space are Pyralux® flexible circuit materials, Riston® dry film photoresists and ImageMaster™ phototooling films. They were all used in flexible circuits that help cameras beam clear, high-resolution signals back to Earth.

And Kevlar® fiber, more commonly known for its protection of law enforcement and military personnel, was used to make a parachute included on the Galileo probe to Jupiter. A “blanket” made of Kevlar® fiber was used to wrap inner walls at the International Space Station to protect it from micrometeorites.

If all that isn’t enough, check out which DuPont products astronauts have worn to the moon.
