What is the material that MX stems are made of?

Ripster just posted some more of his keyboard science on reddit.  He must be reading these threads.  Anyway, here it is:  http://imgur.com/a/Pezs5

Of course he's reading these threads!  Why do you think there is always at least one guest in each thread?

Conspiracy theories...

No need for that. He could just post under another name.

He is totally banned.  And actively monitored.  IP blocking

This is what I don't understand. Why so much hate against that guy and why do people go so far against him. No one will tell me. He didn't scam anyone.

You do  know that IP bans only work against static IPs and even then a person could use a proxy, or use Tor.

Totally spammed the forum (up to about 40,000 posts), criticised everyone and everything, that sort of thing day after day.

I've sometimes wondered how that would actually work, like my home connection can be a bit unstable at times and I get a different IP address every 10 minutes!

Except that proxys are automatically blocked/banned automatically on GH. Not sure about Tor.


On topic; Pretty cool he did the tests but I'd love to get some switches to a lab.

MX stems are made of acetal aka delrin aka POM

+1 

I tried to put Cherry MX stem into quite a few heavy solvents
- Acetone
- Gasoline
- PCB cleaning solvent
So I do believe they are delrin as mkawa confirmed.

And internet cafe's?

Has it been confirmed that the stems are POM? What about Gateron?

That necro. romevi pls.

Pretty much every switch manufacturer uses POM. Nothing about it being softer or harder resulting in smoother or rougher feel. It's all about quality of mould.

Ah, cool. I will carry that information to the mountains.

MX stems are made of acetal aka delrin aka POM

While similar, they are all a bit different.

None handle acids and oxidation well, however POM is very vulnerable to chlorine, which is why POM kitchen knives (and pocket knives) shouldn't be put in the dishwasher. Even the small amounts used in drinking water will cause stress fractures in it. This is made worse when the water is hot. Delrin and Acetal do not experience this, which is why some computer water cooling systems use it in their construction, if you were to make it from POM, your computer would soon be flooded.

In other words, don't clean your POM keycaps in the dishwasher like you can with IBM keycaps.
They may survive a couple times, but eventually they will break down.

Wut?

Polyoxymethylene (POM), also known as acetal,[1] polyacetal and polyformaldehyde, is an engineering thermoplastic used in precision parts requiring high stiffness, low friction and excellent dimensional stability. As with many other synthetic polymers, it is produced by different chemical firms with slightly different formulas and sold variously by such names as Delrin, Celcon, Ramtal, Duracon, Kepital and Hostaform.

[Leslieann]

Polyoxymethylene is a generic chemical makeup, not a specific recipe.

Each has slightly different formulations, just as PLA and ABS has many recipes.
