Its good to see the later production dates have silicone. I'd bet that means the silicone is here to stay. The one I used with nitrile also had date codes from early this year.

I only asked how the determination was made. However, I did this type work for many years. When looking to identify elastomers I would burn them to observe the color and nature of the smoke/vapors. I would also place a small piece in a test tube which I drew into a retort. I then heated the bulb of the retort to produce vapors from the elastomer sample. These were directed out through the tip and onto litmus paper to measure vapor pH. This type of approach are somewhat subject and require interpretation. There are more analytical methods.
Yes, there are more analytical (and complicated) methods, but simply burning the rubber is a good enough way to determine if an ADBV is silicone or nitrile - which anyone here can do with simply a match or lighter.
ADBV Burn Test - Silicone vs Nitrile Rubber
I posted some of this information in another thread, but thought I would dedicate a thread showing the difference between how silicone vs nitrile rubber burns. The tables below show the key differences when the rubber is burned. If you have a doubt on if the ADBV is silicone or nitrile (ie, a...
