What is Teflon? What is Teflon Used For? | DCW

What is Teflon

Cooking was a mess until non-stick cookware was introduced, easing people’s worry and time from cleaning the mess left by food. 

 

Have you ever wondered what the science behind non-stick cookware prevents things from sticking to it? It all comes down to Teflon.


Many probably have heard of the word Teflon before, but what it actually is and where the Teflon part manufacturer can be affordably available is still a mystery to many. Well, worry not. We have dedicated this article just for you to understand the whole meaning and science behind Teflon.

What is Teflon™?

Teflon is a non-stick coating used in non-stick cookware to enable smooth cooking without food particles sticking to the pan. Though Teflon is most commonly associated with cookware, it is also used to make waterproof fabric, medical devices, and various other products.

 

Though Teflon is a brand name or a fancy short form of the actual word polytetrafluorethylene, or PTFE, it is a brand name or a fancy short form of the actual word polytetrafluorethylene, or PTFE. Teflon was given to PTFE by the company Kinetic Chemicals in 1945.

 

PTFE was a well-known unintentional invention created by Roy J. Plunkett, who was on a mission to develop non-toxic refrigerants. He instead invented PTFE, which is still used by many now because of some inaccuracies in scientific calculations.

 

Though you may not realize it, PTFE or Teflon is a form of plastic, which explains its hydrophobic characteristic. It is used to coat objects or equipment and is non-toxic because it does not wear off quickly.

 

The product is sprayed with it and then cooked. This procedure aids in the product’s waterproofing, non-sticking, non-reactive, and non-corrosive properties. It acts as a shield between your product and any external elements that could harm it.


Another interesting fact to notice is that Teflon was first used as a coating for Teflon bellows, valves, and gears, not for generating non-stick clean cookware. It was not until 1961 that it was introduced into the cookware business as a stress-relieving element.

What is Teflon™ Used for?

Teflon is a brand name that is widely used instead of PTFE since it is easier to pronounce. Apart from the fact that Teflon is a common home item in the form of cookware, it also has a vast range of other functions and applications that most people are unaware of.

Before we jump into the main section of the Teflon application, let’s get to know the exact reason why Teflon is very much appreciated in the industry and the unique properties it exudes:

Chemical Resistance:

Teflon offers exceptional chemical resistance, which means the coating does not react with other chemicals when it comes in contact.

Temperature Resistance:

Teflon is exceptionally resistant to extreme high and low temperatures.

Electrical insulating power:

Teflon is a good material with excellent insulating characteristics, which is why it is used to coat electrical components and equipment.

Good fatigue resistance:

Teflon can manage to undergo and resist high amounts of stress and still retain the quality of the equipment it is coated upon.

Low Friction:

Teflon has low friction, which means when employed on manufacturing machinery, the products will easily slide down without getting stuck in the middle.

Extremely Durable:

Teflon coating ensures the longevity of the products for a long time. It’s not affected by ultraviolet rays, oxidation, discoloration, and so on..

Anti-adhesion Properties:

One of the significant and most popular reasons Teflon is highly recommended and used in cookware products is its anti-adhesion properties, which prevent other items from sticking to it.

Low Water Absorption:

Teflon repels water; hence a hydrophobic component is employed in coating equipment and materials that need to be avoided from getting wet.

Now that we’ve established the properties of Teflon, let’s look at a detailed list of the applications of Teflon, as well as the significant reasons and factors that lead to their use:

Cookware:

Cooking equipment and parts tend to get easily messed up by pieces of food sticking to them. Teflon coating on such factors will avoid more mess and make it easier to clean and cook.

Teflon is used as a coating for non-stick fry pans.

It is also used as a coating for coffee maker parts, microwave dishes, and ice cube trays.

Machine Parts:

Machinery parts are usually employed to handle the massive amount of duty every day. To prevent frequent wear and tear, machine parts are generally painted with Teflon, which not proves to be a good coating but also retains the quality of machinery.

It is ideal for making machine parts, such as gears, bearings, pipe linings, joints, slide plates, bushings, Teflon O rings, and saw blades.

Fabric Industry:

It is undeniable that clothes get wet, but what about waterproof clothing? They don’t, and it’s down to Teflon, a simple mechanism used on them. Teflon’s stain-resistant characteristics are also one of the reasons why it is used in the fabric sector.

The nonstick property of Teflon is also used in fabrics and carpets to improve their stain-resistant qualities.

Insulator:

Electric equipment is often coated with materials with strong dielectric characteristics to reduce unwanted electric leakage. Teflon is used to cover electric equipment because of its solid dielectric characteristics.

Teflon is used as an insulator in cables and connector assemblies.

Medicine Industry:

Materials used in the manufacture of medical equipment and parts are typically carefully chosen. Chemical inertness is one of the reasons Teflon is favored for medical equipment manufacturing.

Teflon's properties make it ideal for fabricating prosthetic body components.

Weaponry:

Teflon is also used in coating other weaponry. This is due to the fact that the material reduces the amount of wear and tear on the bullets.

Teflon decreases the wear and tear on the firearm's rifling.

Automobile Industry:

Teflon is also used as a coating for auto parts and machines. This is due to the parts’ ability to protect themselves from harm even when exposed to extreme heat.

Teflon is used to coat automotive plungers, bypass shafts, valves and sleeves.

Personal Care Products:

When it is stated that Teflon is used in everyday products, it implies that it is used in everyday products, particularly personal care products. Teflon is used to coat personal care equipment because of its excellent insulating characteristics, ability to endure heat, and control transmission.

Teflon coatings are applied to curling irons and hair straighteners.

Teflon Forms:

Granular, fine powder and water-based dispersion versions of PTFE are available.

Suspension polymerization in an aqueous solution with little or no dispersion agent produces granular PTFE resin. Molding (compression and isostatic) and ram extrusion are the most common applications for granular PTFE resins.

Controlled emulsion polymerization is used to make fine PTFE powder, which results in white, minute particles. Fine PTFE powders can be paste extruded into thin sections or used as additions to other materials to boost wear resistance or frictional properties.

Aqueous polymerization with more dispersing chemicals and agitation is used to make PTFE dispersions. Coatings and film casting both use dispersions.

Here are the benefits of Teflon parts:

It can withstand both heat and cold.

It possesses excellent electrical characteristics.

TeflonTM can be used to coat a wide range of items.

It has very high durability, preserving its qualities for a long time.

It has a low refractive index, which means that the product's appearance will not alter when exposed to light.

It doesn't biodegrade; thus, it lasts long and is in good condition.

It is water-resistant, making it an excellent water barrier resistant to all humidity levels.

It's a relatively inert substance: Except for molten alkali metals and hot fluorine gas, Teflon is inert to all solvents and chemicals.

Disadvantages of Teflon:

Here are some of the disadvantages of Teflon you should look out for:

It has a very high melting point; thus, it can't be employed in conditions that necessitate incredibly high temperatures.

It has a low electrical conductivity, limiting its use in electronic applications.

It has a low heat conductivity.

It is a weak solvent.

It's a terrible lubricant.

Conclusion

Teflon or PTFE is a significant component that possesses many uses and quality when it comes to coating quality products to retain the quality of the products for a longer time.
