Did you know that Teflon coating was discovered back in1938 by Dr. Roy J. Plunkett completely by accident? Since then, Teflon coating has been used in so many applications and industries, including the cookware industry.
Almost all households have at least one Teflon-coated pan in their kitchens because these pans are extremely resistant to wear and tear. But what is Teflon coating? What are its main advantages and what makes it so popular? Keep reading this article to find out more about Teflon lining and its properties!
What Is Teflon Coating?
Teflon is actually the brand name that commercializes this product, but the coating itself is called Polytetrafluoroethylene or PTFE. There are mainly two types of PTFE coatings such as one-coat PTFE and two-coat PTFE that consists of a primer and a topcoat. They are used in various applications because of their impressive list of advantages.
This type of material has been discovered by Dr. Plunkett by mistake. He was working with a different type of coating when a substance “polymerized” in his laboratory. Dr. Plunkett ran a battery of tests and he discovered that Polytetrafluoroethylene has a high melting point, it’s extremely resistant to high temperatures and it has non-stick properties. Later on, Teflon was advertised and sold as a “miraculous” coating that can take a lot of wear and tear and has impressive chemical and dielectric properties.
What Are the Advantages of Teflon Coating
Teflon coats have numerous advantages such as the following ones:
1. Resistance to Extreme Temperatures
This type of material is popular because it cannot be damaged by extreme temperatures. For example, Teflon can withstand temperatures ranging from- 250 degrees Fahrenheit up to 500 degrees Fahrenheit. That’s why you can easily cook foods on a Teflon coated pan without damaging your cooking utensils or contaminating the food.
The baking industry made a switch from silicone cooking tools to Teflon-coated cookware because it’s much more cost-efficient. Teflon-based cooking tools last longer and they also require less cleaning time, so bakeries can produce more goods.
2. Non-Stick Properties
Another great advantage of Teflon is that it doesn’t. allow foods or other substances to stick to it. This happens thanks to the powerful carbon–fluorine bond that takes place inside the coating. That’s why Teflon pans are advertised as non-sticky and they can be easily cleaned and reused for years.
3. Chemical Resistance
At the same time, Teflon is also capable of not reacting to various types of chemicals and substances. Oxygen doesn’t have any effect on this coating and dangerous chemicals don’t cause damage or abrasions. That’s why Teflon coatings are used in so many industrial applications as it can take a lot of wear and tear.
4. Great Electrical Insulation
Teflon can also be used as an insulator for electrical wires and cables. Thanks to its complex chemical structure, this material doesn’t allow electrons to pass through and it provides a very safe and resilient electrical insulation. On top of that, Teflon also keeps water away and it can be used to make different types of electrical components and systems waterproof.
Exploring The Top Applications Of Teflon Coatings
Teflon is routinely used in the following applications:
1. Computers and Electronics Industries
Thanks to its dielectric properties, Teflon is routinely used to insulate circuit boards in various electronic devices and computers. Electrical insulation is key to make electronic components usable and generally available to the large public. Anything from laptops, desktop computers, smartphones to air conditioning units and microwave ovens use Teflon coatings.
2. Fuel Supply Industry
Different types of fuels such as natural gas or petrol need to be transported all over the world and at different altitudes. This can be easily done using long pipelines that stretch over hundreds of miles, but at colder temperatures, fuel tends to move slowly.
That’s why the fuel industry experts use Teflon coating to line up the insides of fuel pipes. Remember that Teflon has non-stick properties, so it basically allows the fuel to pass quicker through pipes in places with cold temperatures. At the same time, Teflon doesn’t react with the fuel because it has chemical resistance, so it’s the ideal coating for the job.
3. Automotive Industry
The non-stick and non-friction properties of Teflon also make it the go-to material for automotive industries. A wide variety of gears and metal sliders are coated with Teflon, so that friction is reduced and the internal components of a moving engine remain undamaged. Teflon coatings are also used in the aircraft industry thanks to its resistance to extreme temperatures.
4. Medical And Surgical Industries
Teflon coatings are usually used in medical settings for tools and equipment. That’s because this coating type can be treated to be resistant to corrosion and different types of chemical agents. Doctors usually use medical equipment that has been coated with Teflon. In laboratory settings, Teflon also plays a vital role in maintaining a safe and bacteria-free environment.
In certain laboratories, microbial cultures are developed for research purposes. Many of the utensils used by doctors as well as platforms and analyzing tables are coated with Teflon because this material doesn’t interfere with the development of microbes and bacteria.
5. Cookware and Food Industries
As you probably know already, Teflon is often used to coat pans, skillets, and other types of cookware, thanks to its non-stick properties. Commercial kitchen equipment found in restaurants usually use ovens that have been coated with Teflon to prevent food contamination and ensure easy cleaning.
