When it comes to Fluoropolymer Tubing, there are more
than one resin with different make up and slightly different properties. While
FEP and PFA are also commonly used for tubing, the most preferred polymer in
this regard has always been PTFE or what we generally call Teflon.
PTFE Teflon tubing is preferred for several reasons and there
are many factors that set it apart in tubing manufacturing. The first and
foremost of the factors that make it a better option is its low coefficient of
friction. If you didn’t already know it, it has the lowest of all the known
solids. Other than that, it retains the innate properties of fluorocarbon
polymers such as high resistance to chemicals, corrosion, and high
temperatures.
So, what do all these properties mean?
It means that PTFE tubing is actually used in a multitude of
industries and has a plethora of applications. Here are some of the common ones
worth knowing.
Aerospace &Transportation
When it comes to aerospace and transportation technology, PTFE
tubing is usually used inside a stainless steel mesh hose. These hoses work
more efficiently than regular hoses with rubber tubing as Teflon is hardly
affected by the abrasive qualities of fluids used in engines. Due to less
friction, PTFE tubes can greatly improve the overall efficiency.
Medical
This may be one of the least known applications of PTFE tubes,
but they are quickly replacing the regular tubes used for medical purposes. Due
to high lubricity, the tubes are now being used in catheters as they prevent
abrasive damage to any other organ or body part. More and more medical
caregivers and healthcare providers are now switching to PTFE tubes from
regular tubes.
Chemical
Applications
Chemical processing and manufacturing industries require
containers and apparatus that don’t react to the product. Teflon is essentially
the most inert and durable of all substances known and used in industries.
Therefore, PTFE is generally used instead of glass, plastic, metal, or any
other material that might react with the chemical contained in it.
Electronics
PTFE also has excellent dielectric properties that make Teflon
tubes a well suited option when it comes to insulation of high voltage cables.
PTFE tubing is also used for the purpose of isolating conductive surfaces in
capacitors.
