Timely topic

@Ann: Thanks for this informative article on a timely topic.  I had heard that Evonik provided feedstock for as much as 80% of the nylon-12 supply, not 40%, as the article states.  Of course, even 40% represents many tens of thousands of tons.  It's no exaggeration to say that everyone is scrambling for an alternative.

I'm a little surprised you didn't mention Arkema's Rilsan nylon-11, which is based on castor oil and which you covered in an article a couple of months ago.  According to that article, it is already being used in fuel line applications.

Schulman's Schulamid nylon-6,12 is another product worth mentioning.  It's not renewably sourced, but could potentially be a drop-in replacement for nylon-12 in extruded hoses.

The fact that the industry was able to pull together through AIAG and come up with a common test strategy was a major accomplishment.

It will be interesting to see if any of the substitute materials catch on in the long run, or if everyone will go back to nylon-12 as soon as it becomes available again.  There is certainly a potential for long-term use of renewably sourced plastics to increase as a result of this situtation.  It all depends on how well they perform and how much they cost.

naperlou, I was surprised to discover that the industry could go through such a shakeup when only one supplier went offline. Apparently, DuPont and others have already been working on replacements for awhile, as the supply has been tightening due to increased demand from other industries: solar and oil/gas.

Supply chain risks

This situation shows that there are real risks in the global supply chain.  While this global supply may be effecient due to scale, there are many possibilities for disruption.  I would have throght that the consumers of these materials would have plans in place before something like this  happens.

Latest Analysis
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
