About PTFE (Teflon) plastic

PTFE is a semi-crystalline fluoropolymer widely used in many industries because it offers many excellent characteristics. Its chemical name is polytetrafluoroethylene, and DuPont discovered it in 1938. Therefore, PTFE is known as the brand name Teflon®.

PTFE (or Teflon) is an incredibly versatile material with many applications because it offers many excellent characteristics. For example, it provides extreme chemical resistance and thermal stability, making it suitable for seals and gaskets. PTFE also provides a very low coefficient of friction, excellent electrical resistance, and a non-stick surface. However, PTEF provides mechanical strength, but it can be improved by adding glass fiber, carbon, metal, mineral, etc.

PTFE (or Teflon) is usually formed into sheets and rods by compression and extrusion. It can also be made into some complicated parts/components by injection molding and CNC machining.

Frequently Asked Questions about PTFE

Yes, PTFE is generally safe to use in its normal condition. But, if you heat it with a temperature of 300℃ or more, it will pose a health risk.

Yes, PTFE tape is resistant to high heat. It can normally operate at up to 260℃. The melting point of PTFE tape is around 335℃. So, PTFE tape is popular to be used in applications that require more heat resistance.

Yes, Teflon sheets are reusable. You can reuse it multiple times before it requires a replacement. To increase the lifespan of your Teflon sheets, you can rotate their positions.

This will help to manage the proper distribution of pressures and will ensure even wear and tear throughout a long time.

Yes, Teflon is a self-lubricating thermoplastic. So, this high-engineering polymer is widely used in bearings and bushings for its self-lubricating nature. As a result, they don’t need frequent external lubrication.

Teflon is also a wide choice for use in the food industry due to its dry-film lubricant.

Yes, scratched Teflon can be dangerous for human health. Because it can release thousands to millions of microplastics and nano-plastics.

So, you should avoid using any scratched Teflon products to protect yourself from any type of potential toxins.

No, you should not use Teflon tape, particularly in PVC threads. Because Teflon on PVC creates strains that reduce the strength of threads. You can use PVC thread sealant or joint compound for PVC threads.

However, Teflon is very reliable to use in many other applications because of its versatility. 

Teflon and PTFE are actually the same material. PTFE stands for polytetrafluoroethylene, which is the chemical name. On the other hand, Teflon is the brand name for products made from PTFE. So, Teflon is not a different type of PTFE. It’s just a brand name used for this material.

PTFE coating is a plastic coating sprayed on various items. The coating is a fluoropolymer. After the coating is sprayed, it is baked to make the item waterproof, non-stick, non-corrosive, and non-reactive surfaces.

Teflon is highly heat resistant. So, it is widely used in heat-centric applications.

Teflon is chemical resistant which makes it a popular choice for industrial applications.

Teflon has a long service life, and you can reuse it multiple times.

Teflon has extremely low friction, great electrical insulation, low surface tension, and very good weather resistance.

Yes, you can cement PTFE. It is a good adhesive. But you have to acid etch the material or apply plasma treatment first to cement PTFE properly.

Yes, Teflon is both waterproof and oil-proof. Its surface is so smooth that water and oil simply slide off rather than sticking. This feature keeps Teflon surfaces clean and dry by preventing liquids from clinging. As a result, Teflon is highly resistant to both water and oil.

Virgin PTFE is 100% pure PTFE. This has the highest quality of physical properties. This is extremely chemical resistant, and retains its flexibility at low temperature.

On the other hand, mechanical PTFE is reprocessed PTFE. So, it has slightly lower physical properties than virgin ones. Since it has slightly lower physical properties, this is more economical. That is why mechanical PTFE is better to use in less demanding applications.

Teflon coating, sheets, and other products are safe in normal usage for the environment and humans. This can only be harmful to the environment if it breaks down. And Teflon is highly heat-resistant, which confirms it stays normal up to 260℃.

Also, it can degrade at a temperature higher than 300℃. So, it can be said that Teflon isn’t going to harm the environment if you don’t use it in such extreme temperatures.

PTFE has very high heat resistance and can operate at up to 260℃. The thickness of PTFE sheets can range from 3 mm to 100 mm, with a density of 2.16 g/m³. It has excellent waterproof ability, with only 0.01% absorption. The tensile strength is 3,900 psi, and the tensile modulus can reach up to 80,000 psi. The dielectric strength is 285 V/mil.
