There have been few inventions that have
made an impact on the world like that of polytetrafluoroethylene (PTFE), which
is more well-known ithe cooking industry by its trademark commercial name -
Teflon.
What is it?
As noted, Teflon is the
trade name for a plastic material called polytetrafluoroethylene (PTFE), which
was discovered by researchers working for the DuPont chemical company in 1938.
At that time, chemist Roy Plunkett was working on the way to decrease the flammability
of refrigerants that were commonly used in the 1930's. By sheer accident,
Plunkett stumbled upon a chemical reaction known as polymerization, from which
the result was a plastic-type material similar to Nylon, but with different
qualities.
The significance behind Teflon is
that it has many desirable qualities that are not found in most chemicals. For
instance, Teflon is extremely stable, as it does not react with easily with
other substances or solvents; this means that it's safe to handle and work
with, even in the most demanding of conditions. In addition to its non-reactive
nature, Teflon is resistant to electrical current, and it has properties that
make it slick, but not oily.
What is it Used For?
There are thousands of uses for Teflon,
and some are relatively unexpected. In fact, one of the first major
applications to use the advancements brought on by the development of Teflon was
the Atomic Bomb. Teflon’s high resistance to corrosion allowed scientist to use
it as a barrier in the gaskets that held the uranium within the bomb.
The main application of Teflon is in the
cooking industry. The slippery surface that is created with Teflon is used on
the face of high-quality pots, pans, and utensils to prevent food from sticking
to the pan during the heating process. Another prominent application for Teflon
is in the manufacturing of windshield wipers, where the smooth surface created
by the polytetrafluoroethylene allows the rubber fins of the wiper blades to
glide easily across the windshield.
Of course, there are also multiple areas
where Teflon is used in commercial and industrial settings. The steel industry,
in particular, utilizes Teflon to act as an agent against corrosion.
During the steel forging process,
caustic chemicals need to be pumped through industrial hoses and without the
Teflon lining inside these hoses, the chemicals would dissolve the rubber hose
immediately. Over time, even the Teflon will begin to wear through, but it
withstands that caustic nature of the chemicals for far longer than any other
alternative.
SO
There is no doubt that the world would
be a different place without the invention on Teflon, even though its usage
often goes unrecognized. If it were not for Teflon, large manufacturers, like
those in the steel industry would continually need to replace the hoses that
help run the machinery. Also, household items such as cookware and nail polish
would not function at the same level without Teflon.
