PTFE VS Teflon: A Comprehensive Comparison

Hello, people. After doing a lot of research, I have come across a fantastic guide on the differences between PTFE and Teflon. Somehow, they are both, and at the same time, they are not. Let’s get into the details.

PTFE VS Teflon: What Are the Differences?

PTFE is the actual chemical name for a material, and Teflon is the brand name for that same material. PTFE is known for being really stable in different conditions, like heat and electricity.

The world of plastics and polymers is full of jargon and acronyms, making it difficult to understand certain things. One such question that makes people scratch their heads is the difference between PTFE and Teflon™. Essentially, the only difference is the name. PTFE is the abbreviation of polytetrafluoroethylene, and Teflon™ is the trade name of the same polymer.

What is PTFE? 

To understand the difference between PTFE vs Teflon, we need to look closely at PTFE material. Polytetrafluoroethylene is a high-performance fluoropolymer made from two elements – carbon and fluorine. PTFE is a linear polymer of tetrafluoroethylene (TFE) and is manufactured by the free radical polymerization process in an aqueous media with the addition polymerization of TFE in a batch process.

PTFE has many valuable properties, making it suitable for many applications. The most common applications of nonstick coating in kitchen cookware are stain resistance in carpets and fabrics. It is also extensively used in industries like oil & gas, chemical processing, electrical/electronics, construction, etc.

PTFE Properties

Below are some of the typical properties of PTFE:

1. High flexibility
2. Excellent anti-adhesion properties
3. Outstanding resistance to heat and low temperature
4. Good fatigue resistance under low stress
5. Excellent chemical resistance
6. Low dissipation factor
7. Acceptable resistance is light, UV, and weathering
8. Low water absorption
9. Decent electrical insulating capabilities in wet environments
10. Low coefficient of friction

PTFE Applications

The specialty of Fluorinated thermoplastics is that they can be used in applications related to high heat, chemical inertness, high purity, low temperature, non-sticking, and self-lubricating properties. The applications can be seen in automotive, chemical, medical, industrial, electrical, and electronics.

It is a high-performance substitute for materials like polyethylene, which has applications for low-end electrical components but is not suitable for high-end components; however, PTFE, thanks to its excellent dielectric properties and high melting temperature, is ideal for such applications.

What is Teflon™?

As said earlier, it is a trademarked version of Polytetrafluoroethylene. Teflon™ was discovered in 1938 by scientist Dr. Roy Plunkett when he was working on developing a new refrigerant. Later, it was created by Dupont Co. and administrated by Chemours in 1945, and it began selling products made from it in 1946.

The discovery of Teflon was an accident. Der. Rot Plunkett was trying to invent a new refrigerant when he noticed that TFE gs had flowed out of the bottle he was using, but there was no change in the bottle’s weight. To find the reason, he looked into it and discovered that the bottle’s interior was coated with a waxy and stiffy material now known as Teflon.

PTFE VS Teflon: The Differences and Similarities

Simply put, there is no difference between them. So, the winner of PTFE vs. Teflon™ is nothing. There is no reason to compare both; they’re both, in fact, the same thing. Regardless, we must cheer up the existence of such an incredibly versatile plastic material.
