Lubricants are used in a wide range of applications and industries to ensure the smooth operation and longevity of equipment. One lubricant type stands out above the rest thanks to its exceptional versatility: solid film PTFE lubricants. Read on to learn about the key benefits of PTFE lubricants and why they are so highly sought after in industrial settings.
What Is PTFE Lubrication?
PTFE stands for polytetrafluoroethylene: a type of fluoropolymer consisting wholly of carbon and fluorine.
In more general terms, PTFE is a film lubricant that reduces friction between two surfaces without the need for grease or oils. It is specifically designed for areas that require low-friction, corrosion resistance, or dry lubrication. It uses a process that involves a primer coat and a topcoat.
One of the more common uses of PTFE lubricants is in coating items, such as cookware. In fact, PTFE is what we commonly know as the non-stick coating used in frying pans and other kitchen appliances. Teflon® is one such brand well known for using PTFE to make its famous non-stick and heat-resistant products. This use for PTFE lubricants was discovered accidentally in 1938 by an engineer from the DuPont organisation.
You can find different grades of PTFE lubricant which vary depending on the application. For example, the food-grade coating will be different to that of an industrial grade. PTFE RO-59 is often used in industrial settings and deposits a dry PTFE film lubricant that is ideal for long-term sealing.
The Properties of PTFE Lubrication
PTFE lubricants are characterised by a versatile range of properties that make them suitable for many industries. These properties include:
- Self-cleaning ability
- Low friction
- High electrical resistance
- Heat resistance to a wide range of temperatures
- Corrosion resistance
The Advantages Of PTFE Lubricants
There are mant advantages to using PTFE film lubricants. All of these contribute to making PTFE a unique fluoropolymer like no other.
- Non-Reactive – PTFE is a highly inert substance, which means it is not generally reactive to other chemicals. This makes it a great solution for storing reactive compounds or lining materials that will come into contact with reactive agents.
- Reduced Friction – Dry film lubricants like PTFE offer reduced friction. This makes them ideal for anything from cookware to automotive, and industrial industries.
- Electrical Resistance – PTFE lubricant provides high electrical resistance. This enables it for use on electrical cables and circuit boards.
- Durability – PTFE is extremely weatherable and provides superior water resistance. Many industries will use PTFE coating to improve both the performance and the durability of products and objects.
- Temperature Resistance – Using PTFE coating enables different application materials to upgrade to a high-temperature resistance. This means products with a lower temperature resistance can be coated with a more enduring substance. Similarly, PTFE’s high-temperature resistance can also make items non-flammable.
