PTFE, also known under the name Teflon®, is characterised by an exceptional combination of technical properties.
Typical advantages:
- very high chemical resistance
- very good temperature resistance
- very low coefficient of friction
- outstanding sliding properties
- very low adhesion tendency
- low water absorption
- very good electrical insulation
- good weather resistance
- machinable
- cut to size possible
As a result, a white Teflon rod is particularly suitable for sliding, sealing, insulating and chemical applications.

PTFE rod 1000 mm
Martan offers the white PTFE rods as standard with a length of 1,000 mm.
This length is suitable as a starting material for individual technical components and smaller series.
Typical components are:
- bushes
- rings
- sleeves
- plain bearings
- guides
- sealing bodies
- insulating parts
- spacers
- valve components
- pump components
- technical turned parts
If you do not need a full rod, the round material can be cut to the required length.
Select PTFE rods by diameter
The diameter is one of the most important selection criteria for PTFE round material.
Martan stocks various diameters. On the product page, for example, sizes such as:
- PTFE rod 5 mm
- PTFE rod 10 mm
- PTFE rod 20 mm
- PTFE rod 30 mm
- PTFE rod 50 mm
- PTFE rod 100 mm
are listed.
You select the specific available variant directly on the product page.
When making your selection, you should take into account:
- required finished diameter
- machining allowance
- component geometry
- wall thickness
- mechanical load
- subsequent machining
- required tolerances
For turned parts, sufficient material should be allowed for subsequent finishing.
PTFE rod cut to size
Do you only need a specific section of rod?
Then a PTFE rod cut to size can be a sensible option.
Martan also offers PTFE rods as custom cut pieces.
Typical machining processes are:
- sawing
- turning
- milling
- drilling
- CNC machining
A suitably cut PTFE solid rod reduces unnecessary material usage and can simplify subsequent production.
Properties of PTFE rods
PTFE belongs to the group of fluoroplastics and has an exceptional technical property profile.
Typical properties are:
- temperature resistance of approximately −200 to +260 °C
- very high chemical resistance
- extremely low friction
- very good sliding properties
- low surface adhesion
- hydrophobic surface
- very good electrical insulation
- high weather resistance
- low flammability
- low mechanical stiffness compared with many engineering plastics
It is precisely the combination of chemical resistance, temperature resistance and low friction coefficient that clearly distinguishes PTFE from many other engineering plastics.
PTFE rod for high temperatures
PTFE has a very wide temperature service range.
Martan states a range of approximately −200 to +260 °C.
As a result, the material is suitable for technical applications in which conventional plastics are no longer suitable due to very low or high temperatures.
Actual suitability should always be verified on the basis of:
- service temperature
- duration of load
- mechanical load
- component geometry
- medium used
.
Chemical-resistant PTFE rod
One of the most important properties of PTFE is its very high chemical resistance.
As a result, the material is particularly suitable for components that come into contact with aggressive media.
Typical components are:
- valve parts
- pump components
- sealing elements
- bushes
- guides
- lining components
For specific chemicals, resistance should always be verified taking into account the medium, concentration and temperature.
PTFE rod for sliding components
PTFE has a particularly low coefficient of friction and very good sliding properties.
Round material can therefore be used to manufacture, for example:
- plain bearings
- bearing bushes
- guide bushes
- sliding rings
- sealing rings
- friction elements
The low adhesion tendency can also be of interest in applications where adhesion is to be reduced as far as possible.
PTFE rod for electrical insulation
PTFE has very good electrical insulation properties.
Round material is therefore also suitable as a starting material for:
- insulating bushes
- spacers
- insulating rings
- support elements
- electrical insulating parts
Even at higher temperatures, the electrical properties remain of interest for many technical applications.
What are PTFE rods used for?
White PTFE rods are used in numerous demanding technical fields.
Typical fields of application are:
- chemical plant construction
- mechanical engineering
- plant construction
- electrical engineering
- pump technology
- valve technology
- sealing technology
- technical apparatus
Typical components are:
- bushes
- plain bearings
- sealing rings
- guides
- insulating parts
- valve components
- pump components
- spacers
- technical turned parts
Turning PTFE rod
PTFE can be machined well by cutting.
Turning is particularly suitable for producing rotationally symmetrical components such as:
- bushes
- rings
- sleeves
- sealing bodies
- plain bearings
- spacers
Due to the material properties, particularly sharp tools and suitable cutting parameters should be used.
Temperature and clamping conditions can also influence the dimensional accuracy that can be achieved.
Milling and drilling PTFE rod
In addition to turning, PTFE can also be milled and drilled.
This allows, for example:
- cross holes
- grooves
- surfaces
- recesses
- fastening holes
to be introduced into the component.
For complex geometries, CNC machining can be a sensible option.
PTFE rod or PTFE sheet?
The suitable semi-finished product form depends on the subsequent component geometry.
PTFE rods are particularly suitable for:
- bushes
- rings
- sleeves
- rollers
- turned parts
- rotationally symmetrical components
PTFE sheets are particularly suitable for:
- seals
- linings
- insulating sheets
- guide plates
- flat milled parts
You can find suitable flat material under PTFE / Teflon® sheets.
PTFE or PEEK rod?
PTFE and PEEK both belong to the high-performance plastics, but differ significantly in their mechanical properties.
PTFE offers particular advantages in:
- very low friction
- very high chemical resistance
- low adhesion tendency
- electrical insulation
PEEK offers advantages in:
- higher stiffness
- higher mechanical strength
- higher dimensional stability
- highly loaded precision components
If high mechanical load capacity is the priority, you can find suitable variants under PEEK rods.
PTFE or POM-C rod?
For classic mechanical precision parts, POM-C can be an alternative to PTFE.
POM-C offers in particular:
- high stiffness
- good dimensional accuracy
- very good machinability
- good mechanical load capacity
PTFE, by contrast, offers advantages in:
- chemical resistance
- temperature range
- friction behaviour
- electrical insulation
You can find suitable material under POM-C rods.
