Q&A How does temperature impact the properties of PTFE materials?

February 28, 2017


We are often asked about what can be expected when you use a Rulon bearing or any PTFE in high temperatures. Many things can occur, and it varies from material to material based on the use of different fillers. Let’s review:

PTFE and High-Radiation Environments: 5 Important Facts

January 31, 2017

PTFE and High-Radiation Environments

We’ve had many questions about the connection between PTFE materials and high-radiation environments. Often, when working in these conditions, engineers turn to fluoropolymers like Tefzel (ETFE) as a preferred material instead of PTFE. But before you make a final material decision, let’s review some key facts about PTFE in this environment.

Chlorine, Corrosion and the PTFE Bearing Connection: A Case Study

Our recent post on PTFE and Rulon in water applications generated some solid interest. Today I want to share a case study of how PTFE-based bearings have resisted corrosion in a submerged chlorine tank as a replacement for Torlon ― all despite the fact that PTFE is not generally recommended for chemical exposure.

Rulon W2

I’ve been getting a lot of questions recently about PTFE-based materials like Rulon for use in water applications. Generally, PTFE is not a good solution for water-lubricated applications. Today I want to share the results of some independent testing we conducted.

Q&A - Can you review amorphous vs. crystalline polymers?

February 12, 2015

The key attributes of crystalline vs. amorphous polymersA recent customer visit found us reviewing the attributes of amorphous vs. crystalline polymers. I thought I’d share the information as a good refresher on polymers and PTFE. 

So what are the key attributes of crystalline vs. amorphous polymers?
