If you’re in the Industry of non-stick coating like ourselves at Product Release, PTFE is a material that’s your ‘bread and butter’.
For those who aren’t though…PTFE sounds like it could be a different language.
So, for all those who aren’t fluent in the language of ‘non-stick’, PTFE stands for Polytetrafluoroethylene.
It’s used as a non-stick coating, lubricant and it’s frequently used in the medical industry as it interferes with the ability of bacteria and other infectious agents amongst other uses.
Now, PTFE isn’t the only kid on the block in this industry, however, it is often the go-to option.
So, that begs the question Why is PTFE so popular?
Apart from being amazingly flexible, PTFE is resistant to electricity, heat, and chemical reactions, making it a stable material for erosive and tough environments.
It’s also strong so can survive against high pressures, where many other competitive materials fail.
And that’s not all…
The other benefits of using PTFE are:
- Its chemical resistance is one of the highest among all its competitors.
- It can be used at high temperatures and is stable at large temperature variations.
- It has a high strength to weight ratio.
- Its dielectric strength allows it to be used for insulation purposes for a wide range of currents.
Now, of course, there are two sides to every story and there are times when PTFE may not the way to go…
The reasons for not using PTFE are:
- PTFE is not the best material for making rounded or asymmetric parts.
- If very high accuracy is required for making the parts, PTFE is not best suited.
- PTFE shouldn’t be used for high-pressure mechanical joints because it’s likely to get deformed due to being softer than other plastics.
- PTFE should be avoided for high precision manufacturing because it’s not easy to get the best finish.
So, as you can see, PTFE isn’t perfect…But what is?
And although it’s got certain limitations, PTFE still finds a variety of applications in several industries, making it one of the best manufacturing materials for non-stick solutions.
Well, I’m sorry to disappoint you, but here at Product Release, we think PTFE is far from ugly. We use it in countless processes for our clients to get results for all their non-stick needs.
