PTFE is a fluoropolymer categorized in the group of plastics made up of carbon and fluorine atoms. It is a material that is good in resisting heat, low coefficient of friction and chemical resistance.
This guide highlights some fundamental aspects about the temperature range of PTFE.
RPTFE Temperature Limit
RPTFE is PTFE strengthened with carbon, glass, or bronze having a range of -450C to 2300C service temperature.
Usually, it is suitable for steam and thermal fluid applications due to its low coefficient of friction. Besides, it is a good chemical resistant that offers an improved life cycle.
Virgin PTFE Temperature Range
PTFE has excellent thermal insulation properties with a low coefficient of friction.
Its mechanical properties are low compared to other plastics and have a wide useful temperature range of -730C to 1490C.
Teflon Melting Temperature
Teflon is a synthetic plastic with a density of 2.2g/cm^3. It has a melting point of 3270C.
Glass Filled PTFE Temperature Range
Glass filled PTFE is dimensionally stable and wear resistance.
It has an extremely good chemical resistance of -2600C to +2600C temperature range.
PTFE Softening Temperature
PTFE has a co-efficient linear thermal expansion of 7.50F and melting temperature of 6350F
Graphite Filled PTFE Temperature Range
Graphite is low in friction and good in self lubrication. It has a temperature range -350◦F +500◦F.
How Temperature Affects PTFE Properties
The molecular composition in PFTE reacts differently when exposed to high temperatures. Once deformation takes place, it is difficult to regain its actual stature.
Usually, PFTE starts to transition at 78◦F. However, this tendency is good in applications that require tensile strength.
PTFE Thermal Stability Range
The polymer structure in the PFTE makes it the best thermally stable component to maintain its properties due to its high C-C bond energy.
How PTFE Temperature Range Determines Uses
It is commonly used in making nonstick kitchen cookware such as pans and pots. Of course, this is due to the high thermal stability temperature range of -400◦F to 500◦F.
Other applications include microwaves, electrical insulators, gas line pipes, coffee makers, chemical processing systems, gasket lining, solar pane accessories, etc.
For any application, you can choose PTFE sheets, PTFE rods, or PTFE pellets.
Conclusion
PFTE is a synthetic material with superior nonstick properties that cannot be compared to other plastics.
With its high-temperature stability, low coefficient of friction, and complete chemical resistance, various fillers can be added on to it to improve its performance.
