PTFE rods (Extruded)

PTFE rod has excellent resistance to most chemicals and solvents and is capable of operating at high and low temperatures - up to 260°C. The PTFE rods also have a very low coefficient of friction and are commonly used in food contact applications. Rods of PTFE provides good thermal stability and has good electrical properties, but are not suitable for wear application and is difficult to bond.

Advantages:

Extremely high chemical resistance
Wide temperature range - maximum service temperature 260°C
Low friction and low adhesion
Resistant to Radiation
Excellent dielectric performance

Note

The largest PTFE rods supplied have a size tolerance of ±5 mm. For applications requiring an exact diameter and roundness, we recommend grounded or calibrated rod. This PTFE rod is processed after extrusion so desired diameter and roundness are guaranteed.

Applications:

Slide bearings, insulators and rollers, gaskets.

FAQ

What is the maximum temperature PTFE rods can withstand?

PTFE rods can operate at temperatures up to 260°C.

Are PTFE rods suitable for food contact applications?

Yes, PTFE rods are commonly used in food contact applications due to their low coefficient of friction and chemical resistance.

Can PTFE rods be bonded easily?

No, PTFE rods are difficult to bond due to their low surface energy.

EXPERT ADVICE: When using PTFE rods in applications, ensure that they are not subjected to wear as they are not suitable for such conditions.
