Although it’s been around for nearly seven decades, Teflon® coating services remains highly popular for a variety of applications. Teflon® production surpassed 240,000 tons by the year 2017. Back in the late 40s, only about 900 tons of the substance were produced.
PTFE coating is a fluorocarbon solid, making it resistant to corrosive chemicals and extreme temperatures for both hot and cold, UV ray resistant, and low friction. It also provides good insulation from electricity and doesn’t absorb water. Its legacy in industrial applications spans over 80 years. Continue reading for how PTFE is made, its history, and how it is used today.
Teflon® coatings have a number of properties that make it useful to many industries. PTFE coatings are resistant to corrosive chemicals, provides good insulation from electricity, doesn’t absorb water, can withstand extremes of heat and cold, resists UV rays, and creates little friction. Many industrial Teflon® coatings can withstand temperatures as low as -250ºF without loss of physical properties and can operate continuously at temperatures up to 260°C/500°F.
In addition to its uses in cookware, industrial Teflon® coatings are often used in the automotive industry, cabling materials, optical devices, pharmaceutical applications, pipes, valves, and more. Companies interested in how Teflon® can work with their products should contact Orion Industries, a DuPont Licensed Industrial Applicator that specializes in applying industrial Teflon® coatings to various products.
How a PTFE Coating Works
A PTFE coating’s unique makeup is what provides it with the non-stick, non-friction, and dielectric properties that make it useful in so many applications. Teflon® coating is a fluorocarbon solid, meaning that it has a high molecular weight made up solely of carbon and fluorine. This make up makes it resistant to water, gives it a low friction co-efficient, and makes its other useful properties possible.
Uses of PTFE Coatings
While most people think of skillets and pots when they think of Teflon® coatings, the truth is that half of all PTFE production is used for wiring in aircraft and computers. PTFE’s dielectric properties and high melting temperature make it ideal for insulation cables and connector assemblies. Printed circuit boards used at microwave frequencies also often use PTFE as insulation. Good insulation is vital to safety, and that’s why so many industries trust PTFE.
PTFE, or Teflon®, coatings provide protection against water, corrosion, friction, and more. In the 70 years since its discovery, a variety of industries have come to view Teflon® as the go-to coating for thousands of applications.
