Dr. Roy J. Punkett, Chemours chemist, on april 6, 1938 in a laboratory in Jackson New Jersey.
Was working with freon, refrigerant gases product of Chemours.
When reviewing a compressed frozen sample of tetrafluorethylene.
He and his collaborators discovered that the sample had spontaneously polymericed in a white colored wax forming polytetrafluorethylene.
PTFE is inert to practically all chemical products and is considered the material with the highest anti-adhesion that exist.
These properties have made it one of the most valuable and versatile technologies ever invented, whitch contributes to significant advances in areas such as aerospace, communications, electronics, industrial processes and architecture.
