Why PTFE Insulation?

PTFE is used around the world every day as a coating material for a number of reasons, all of which come together to make it a resilient and reliable material. As an insulator, it is prized for the strength of its carbon-fluorine bonds that are incredibly flexible and non-reactive. PTFE is also hydrophobic, ensuring that water and substances with water in them will not react with a PTFE insulated wire.

In addition to its chemical properties, PTFE insulated wires cannot be cross-linked and are not subject to memory or creeping. This ensures that bending, flexing, and stressing do not move or deform the PTFE coating. This makes it an incredible material for insulation, ensuring that your PTFE insulated wires have the long flex life that allows them to remain reliable for years to come.

In addition to our PTFE insulated wires ‘ resistance to creeping and deformation over time, PTFE insulated wires also provide extremely reliable dielectric properties, making miniature PTFE insulated wires a popular choice for PCB applications and a much more effective, high performance, and temperature resistant alternative to polyethylene.

PTFE Insulation Features: Fast Facts

  • High dielectric strength
  • Low dissipation factor
  • Unaffected by exposure to moisture, humidity, and liquid
  • Very high operating temperatures
  • Silver-plated conductors or your choice of conductor
  • PTFE insulated wires are not subject to creeping or deformity over time
  • PTFE insulated wires are suitable for a wide frequency range
  • Provides resistance to UV radiation, stress, mold, and chemicals

PTFE insulation typically provides attractive space-saving advantages over other less advanced insulators.

The Main Properties of PTFE

If you were trying to invent a highly flexible, chemical resistant, thermal resistant, non-stick and electrically resistant material, and it hadn’t already been done, you’d be hoping you could come up with a material somewhere nearly as good as PTFE is in these areas.

PTFE’s melting point is around 327°C, and pure PTFE is almost totally chemically inert, highly insoluble in most solvents or chemicals, and thermally stable enough to be used between-200°C&+260°C without degrading.

Other useful PTFE properties are its high flexural strength, even in low temperatures, high electrical resistance and dielectric strength, resistance to water (owing to fluorine’s high electronegativity), and low coefficient of friction. PTFE’s density is also very high, at 2200 kg/m3.

In fact, beyond reaction to some chemical agents and solvents (for example, chlorine trifluoride, cobalt (III) fluoride, xenon difluoride, or elementary fluorine if at high pressure and temperature), the only factor to be taken into consideration when using PTFE is that it does not have good resistance to high energy radiation, which will cause the breakdown of the PTFE molecule.

Modified PTFE properties

In addition to pure PTFE, there are two co-polymers which are equally as useful as PTFE, but with some different properties.

PFA or Perfluoroalkoxy has very similar properties to PTFE in that it is very chemically resistant, flexible, and thermally stable (with continuous use up to 260 degrees C), but while PTFE does have some tendency to creep, PFA is creep resistant and is excellent for melt-processing, injection moulding, extrusion, compression moulding, blow moulding, and transfer moulding.

TFM, known as PTFE-TFM, is poly tetra fluoro ethylene with perfluoropropyl vinyl ether as an additional modifier, giving a denser material which is stiffer, also creep resistant like PFA, and weldable.

Filled PTFE

Pure PTFE can deform badly under a load, but the use of fillers can help with this, though it should be noted that not all filled PTFE is suitable for use with food.

Adding a filler to PTFE can increase its strength, improve resistance to abrasion, add electrical conductivity, and more; however, adding fillers can also reduce some of the advantageous PTFE properties, such as chemical resistance which will be limited by that of the filler. 

Advantages and benefits of using PTFE

The biggest advantage of PTFE is its versatility, and the range of applications over so many products and different industries for this material is staggering.

The use of PTFE can have massive benefits in manufacturing and engineering, not just in making tubes or liners for handling or storing corrosive chemicals, but by coating parts such as bearings or screws to increase the lifetime of both the parts themselves and the machinery they are part of.

A PTFE-coated screw will be resistant to corrosion, due to PTFE’s ability to repel water and oil, and lubricated by the material to smoothly drive into whatever surface you are fastening to, with reduced friction, resulting in less wear on both the screw and the surface, and a longer-lasting, more secure finish.

Friction and wear can also be factors with bearings, and a PTFE coat can give the same benefits as with coating screws, with the additional advantage that the coating will also be heat-resistant.

It’s clear that longer-lasting, higher-performance parts can add to the efficiency of any machinery, reduce the need to constantly acquire replacement parts, both saving money and the time needed to fit the replacements, as well as reducing waste. This will also reduce maintenance needs as there are less likely to fault with the equipment, and also greatly reduce, or even eliminate, any expensive manufacturing downtime due to faults or repairs.

Cleaning of equipment can also be reduced in some cases as a PTFE coat is non-wetting, facilitating self-cleaning of parts.

Teflon Textile finishes can even help the environment, because, when applied to fabric, the finish will repel water and oil stains, reducing the need to use dry cleaning, and fabrics will also dry more quickly, using less energy with tumble drying, and last longer due to reduced wear.

With the added advantages that PTFE is non-toxic, has only a minor contraindication for humans from polymer fume fever (only if the temperature of any Teflon-coated pans reaches 260 degrees C), and is FDA approved and food-safe, this material really is of great benefit in many different areas.

Interesting uses of PTFE

As well as coating everything from pans to bearings, PTFE is also used to stop insects climbing walls as the material is so ‘non-stick’ that insects (and even geckos) are unable to grip.

The polymer is used frequently as a coating on catheters to inhibit bacteria and infections and is also used as a graft material in surgery.
