Polytetrafluoroethylene or PTFE, better known as Teflon庐 can be used for Slide Bearings in its pure form, known as Virgin Teflon庐, or as Fiberglass Infused Teflon庐.
Teflon Slide Bearings have a very low coefficient of friction, high compresssive strength and can remain stable at temperatures up to 400掳F. For the standard expansion joint in a steel structure these are ideal properties in that most assemblies never approach 400掳F and with a compressive strength range of 70 psi to 2,000 psi, the bearing can be designed to accommodate almost any weight load.
While Virgin PTFE has the required attributes for a Slide Bearing it is not as durable as Fiberglass Infused PTFE or Fluorogold庐. It also has a tendency to indent its silhouette into the opposing Teflon庐 surface. For this reason designs using Virgin PTFE should consider;
- Upgrade to Fluorogold庐 or Fiberglass Infused Teflon庐
- If Virgin PTFE is designated, it should be on the lower member, with the upper being polished stainless steel.
