We think this blog post by Poly Fluoro provides a great overview of the strengths and attributes of PTFE in a variety of applications. We’ve reprinted it below in its entirety so that you can benefit from the article as well. You may view the original on Poly Fluoro’s website, here.
Amorphous vs. Semi-Crystalline Polymers
High temperature polymers are divided into two categories: amorphous and semi-crystalline.
Guide to Selecting a Polymer Bushing
The process for selecting a polymer bushing isnt that difficult, but it does involve quite a bit of information about the bushing application before you begin.
The Differences Between Thermoplastics and Thermosets
Polymers are divided into thermosets and thermoplastics.
5 Recommended Materials for Seal and Bearing Applications in Food Processing
There are various challenges for designing polymer seals and bearings for the food industry, such as FDA regulations if the seal or bearing will be in contact with food products or the ability to withstand intensive cleaning and sterilization.
Famous Seal Disasters in History: Space Shuttle Challenger
There are many myths related to the Challenger disaster, but one fact remains: the explosion could be traced back to an o-ring that failed to seal in the gases it was responsible for.
Cryogenic Seals for LNG Marine Loading Arms
One of the major challenges in working with LNG (liquefied natural gas) is transporting it. LNG is stored and transferred at cryogenic temperatures which can be a major challenge when it comes to designing seals.
Guidelines for Machining PEEK, PAI and Other Advanced Polymers
Annealing
Machining and finishing of high temperature polymer materials can release residual stress. It is recommended that a second annealing is performed on the semi-finished stock prior to the machining process. Annealing can limit dimensional changes, remove stress, and increase levels of crystallininty.
3 Key Challenges in Machining Plastics
The basic principles behind machining engineering plastics are the same as those behind machining metals, but there are some key characteristics of plastics that make machining them to tolerance an interesting challenge.
Relieving Stress in Plastic Materials
Many engineers are familiar with the need to anneal metals for stress-relieving, but not so many engineers know about annealing plastics. In this blog post, we are going to talk about the subject of annealing polymers.
