PTFE and Modified PTFE Bellows: What’s the Difference?

Polymer Bellows

Polymer bellows are found in quite a few industries, including petrochemical, medical, pharmaceutical, chemical, and the food industry.  Because of its chemical inertness, low spring life, and long flex life, PTFE is often the material of choice for polymer bellows.  However, it isn’t the only option.  In this article, we are going to compare PTFE and TFM.

Tribological Properties for PEEK: Bushing and Bearing Applications

PEEK Increasingly Popular

Polymer bushings have found widespread acceptance because they are typically low friction, light weight, relatively inexpensive, have an extended service life, and can be self-lubricating.  Most polymer bearings and bushings are made from a form of PEEK, PTFE, Nylon, or UHMW PE.  PEEK is becoming increasingly popular because it offers a good balance of chemical, heat, and wear resistance; and is, versatile when it comes to manufacturing.
