Key Advantages of PTFE for Bellows

Posted On March 15, 2017

Bellows can perform a variety of tasks in a mechanical system, including vibration dampening, absorption of displacement in a piping system, compensating for misplacement and misalignment, and the protection of brittle components (glass, graphite, glass-lined steel, etc.).

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

Posted On February 26, 2016

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.

What are bellows used for?

One of the primary uses of bellows is to absorb dimensional changes due to thermal effects, which is very useful when used high temperature flows such as steam.  Bellows also serve to dampen vibration in the system caused by rotating components, protect sensitive and brittle processing equipment, and to absorb shock loadings

PFA and TFM–to PTFE as Excellent Material Choice for Bellows and Diaphragms

Posted On July 10, 2015

Polymer Bellows and Diaphragms

PTFE (polytetrafluoroethylene), aka Teflon, is typically the first choice polymer for bellows and diaphragms, but did you know that PTFE isn’t the only polymer you can choose from?  In this article we are going to compare two other polymers – PFA and TFM – to PTFE as a material choice for bellows and diaphragms.

7 Things about PTFE Bellows You Need to Know

Posted On April 29, 2015

The primary purpose of a typical expansion bellows is to isolate a fluid from neighboring components.  Bellows are used in a variety of applications, including pulse dampeners, HVAC systems, pharmaceutical processing, pollution control, and piping systems.  PTFE (polytetrafluoroethylene, or Teflon) is an ideal material for bellows applications, and in this post we are going to explore seven things every engineer needs to know about PTFE bellows.
