Polytetrafluoroethylene or PTFE, also known
as Teflon is a versatile ivory-white and opaque plastic fluoropolymer; it is
composed of the free-radical polymerisation of numerous tetrafluoroethene molecules and is suitable for a number of
applications in industries such as aerospace, the food and drink industry, telecoms and pharmaceuticals.
PTFE tubes or PTFE hoses are made into different sizes or filled with carbon, carbon, stainless steel or many other materials to increase the wear resistance and strength.

Properties
of PTFE
The main properties of PTFE are that it is
highly flexible, thermally resistant, chemical
resistant, non-stick and it is also composed of electrically resistant material.
The melting point of PTFE is around 327°C, and pure PTFE is also chemically inert, and also highly insoluble in most solvents or chemicals. It is also thermally stable and thus can be used between -200 degrees C and +260 degrees C without changing.
Other useful PTFE properties which set it apart from other pipes are its flexural strength, which is evident even in low temperatures. Besides its flexural strength, it has high electrical resistance and also dielectric strength, resistance to water because of fluorine’s high electronegativity and also the low coefficient of friction. That’s not all, PTFE’s density is pretty high, at 2200 kg/m3.

PTFE is really versatile, and it boasts of a wide number of applications. The benefits of PTFE can be utilised in manufacturing and engineering, for making tubes or liners and for handling or storing corrosive chemicals, also for coating parts such as bearings or screws to increase the shelf life of both the parts themselves and also the machinery they are part of.
A PTFE-coated screw will be corrosion-free, as PTFE can repel water and oil, and is also lubricated by the material to smoothly drive into the surface you are fastening to, with reduced friction, thus resulting in less wear and tear of the screw and the surface, and a secure and long-lasting finish.
A PTFE coat can extend the same benefits to screws, as it coats the screw it also makes it heat-resistant.
It’s true that the high-performance parts can ensure efficiency in machinery and reduce the need to replace parts, so it saves money and time and also reduces waste. This will further reduce maintenance needs and any expensive manufacturing downtime because of faults or repairs.
Cleaning of equipment can be drastically reduced in a few cases as a PTFE coat is non-wetting, thus facilitating self-cleaning of parts.
Add to that Teflon is also environment-friendly because, when it is applied to fabric, the finish will repel water and also oil stains which reduces the need to use dry cleaning, and fabrics will also dry up more quickly, with less energy with tumble drying, and it also lasts longer due to less wear and tear.
PTFE is non-toxic, except for humans from polymer fume fever that is, only if the temperature of any Teflon-coated pans reaches above 260 degrees C. It is also FDA approved and food-safe, so this material has a great many benefits and can be used in many different areas.
