Strong, Low Friction material better than teflon?

Click For Summary

Discussion Overview

The discussion revolves around the search for a non-metallic low-friction material that is stronger than plastic and can serve as a surface for plastic parts to move over, as an alternative to Teflon, which is experiencing unexpected wear.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant is seeking a stronger, low-friction alternative to Teflon due to wear issues with the current material.
  • Another participant questions whether the wear is occurring on the Teflon or the plastic parts, suggesting that the choice of Teflon hardness may depend on which material is wearing.
  • A participant confirms that the Teflon is indeed wearing.
  • Several materials are proposed as alternatives, including Devatex 1, Orkot TXM-M, Tenmat T814, and Lubron, as well as bar stock from iglide called J350.
  • Rulon is mentioned as another potential alternative with various formulations.
  • There is a suggestion that the plastic parts may contain abrasive fillers, such as glass fiber, which could be contributing to the wear of the Teflon.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the cause of the wear or the best alternative materials, indicating multiple competing views and unresolved questions regarding the material properties and application requirements.

Contextual Notes

There are limitations regarding the assumptions about the wear mechanisms and the specific requirements for strength and friction characteristics of the proposed materials.

I'm working on an engineering problem where we are using Teflon as a low-friction material as a surface for plastic parts to move above. However, the material is wearing faster than expected due to the plastic rubbing away at the Teflon. Is there a non-metallic material that has equal or better low-friction characteristics to Teflon, yet it is stronger then plastic?
 
Engineering news on Phys.org
It's unclear if the Teflon or the plastic parts are wearing?
If it's the Teflon wearing, use a harder Teflon, if it's the plastic parts, use a softer Teflon.
Why do you need good strength? Is the low friction surface also structural?
 
The Teflon is wearing.
 
You could use Devatex 1, Orkot TXM-M, Tenmat T814, Lubron or bar stock from iglide called J350 or something similar.
 
Look at Rulon, several different flavors.
 
Maybe the plastic parts that abraid the Teflon are reinforced with glass fiber or some other abraisive filler?
