Ultem® Mule
Here is a teaser for a new build….
Ultem®
High strength plastic with outstanding electrical and high service temperature properties
Ultem® (polyetherimide) is a semi-transparent high strength plastic material that can operate in high service temperature environments. Ultem® is resistant to hot water and steam and can withstand repeated cycles in a steam autoclave. FDA compliant grades of Ultem® are available. For Ultem® chemical resistance view our chart.
Ultem® has outstanding electrical properties, with one of the highest dielectric strengths of any thermoplastic material.

Re: Ultem® Mule
Wow. Fascinating plastic. Can you use regular epoxy with it? I would guess that one would need an Ultem version of epoxy to really sick it on and maintain the food grade compliance. A plastic that can resist 200c or 392f was outstanding to me, until I googled it and found other plastics that withstand 700c. I'm in Canada eh.
What I would really really like is a plastic or other material that absorbed and retained heat. Currently, it is -37c or -34.6f where I live. It would be amazing to have a knife that stayed warm in a pocket, then transferred that heat to your hand when in use. But I side track.
This looks like a fantastic build, and I really like the translucent scales. I am also a super fan of knives that can be easily sterilized. So, I'll be following this thread.

Re: Ultem® Mule
High heat epoxy is not that uncommon. Most long cure epoxy products have a relative good heat tolerance.ykspydiefan wrote: ↑Mon Jan 03, 2022 2:09 amWow. Fascinating plastic.

I use 12 hour epoxy mostly because it is better at waterproofing than most quick cure products
Lack of 100% waterproofness is common to all mercaptin based “quick cure” epoxy formulations.
For this build I will use a High Heat extreme epoxy that will go well with the Ultem. Only issue is it may cure a slight yellow which won’t matter one bit.
Love trying new handle materials and I must say Ultem is one of those.
This was a labour to get and quite expensive but it will be worth it and I have enough for 10 or so handles. The rod was a 5ft length so expect to see it as pins on some wooden handles in the future

Re: Ultem® Mule
I thought this was gonna be a request for a Mule made of Ultem. This makes way more sense.
Re: Ultem® Mule
Same, it seemed weird, ultem sounds more like a fruit than a steel!
Seems interesting though, I like the fact that's it's like 50% opacity ! Looks a bit like amber.
In the collection : Lots of different steels, in lots of different (and same) Spydercos.

Re: Ultem® Mule
Found when I started looking there was Several sources and several levels of Quality. Some of the cheap stuff turned out to be cloudy and a off looking colour. The stuff I have used wasn't cheap and now I know why the beads made out of it are so expensive
You want the unfilled as there is a glass filled version as well
This was sourced from a specialist plastic manufacturer and supplier that took some emails to allow me to buy it.. (had to buy a whole sheet which was 12" X 12" and a 5ft rod
Oddly I got a end piece with the name of the manufacturer on the sheet
If your keen I will shoot you a PM with details

Re: Ultem® Mule
Think it detracts from the coolness of see through..
Here with scale material glowing…

Re: Ultem® Mule
Thank you. I like it both ways, but fully translucent is best.

Re: Ultem® Mule
Cool use of a very cool plastic!
It's my favorite material for guitar picks. It doesn't wear like nearly all other materials I've tried (nylon, celluloid, delrin) and has a hardness that allows for thinner picks without the flex.
I'd bet it would take some checkering or texture really nicely, but I think I'm going to like the looks of it when smoothed and shaped. Nice!
