PTFE Properties

History
Polytetrafluoroethylene (PTFE) resin is in a class of paraffinic polymers that have some or all of the hydrogen replaced by fluoride. The original PTFE resin was first discovered on April 6, 1938 by Dr Roy J. Plunkett. While working at DuPont's Jackson Laboratory in New Jersey on another project, Dr. Plunkett found that a frozen, compressed amount of tetrafluoroethylene gas had polymerized into a waxy white solid substance, forming polytetrafluoroethylene (PTFE). DuPont registered the original PTFE resin under the trademark Teflon® in 1945, and the first commercial products were sold under this trademark in 1946. Interestingly, PTFE was produced on a limited scale in the early 1940s, and was used shortly thereafter by the Manhattan Project in containers for highly corrosive elements during uranium separation experiments
