On the morning of April 6, 1938 a chemist at E.I. du Pont de Nemours and Company, by the name of Roy Plunkett and his assistant Jack Rebok stumbled across one of the  most impactful discoveries of their lives. The day before the two chemists were testing and analyzing chemical reactions of tetrafluoroethylene, a gas used in refrigeration. Wednesday morning they walked into their lab and discovered the pressurized bottle sized cylinder of gas appeared to be empty. Roy was baffled so he unscrewed the valve from the cylinder and carefully tilted it upside down to find a white powder, he then cut it open to find a substance that was packed on the lower part and the bottom of the cylinder, Poof! PTFE had been discovered. The tetrafluoroethylene gas had polymerized into polytetrafluoroethylene and was introduced in 1946 as Teflon. In 1956 we saw the introduction of FEP and later in the early 70s PFA.

Coiling is not just science.

We have fabricators with over 35 years of coiling history that will agree even with the aid of engineers and computer models it is 5% art, and you will see this in our craftsmanship. Over the years we have developed multiple proprietary processes that are used in coiling and achieving tolerances unheard of in the industry today.

Common terms used in coiling.
