a lot of the new stealth planes being trialed in the US are actually rumored to be made from uhmwpe. they dont call it that, they call it "thermoplastic", but its pretty obvious to me thats what theyre referring to in industry. the f22 and f35 were made from "thermoset" plastics, which includes a lot of the epoxy and carbon fiber techniques that boeing and lockeed martin has gotten pretty good at. the main issue with thermosets in the context of avieation development is the R&D that has to go into perfecting the kilns/curing pressure vessels.... that is unless youre as crazy as boeing and invent hot spooling prepreg like on the 787. didnt work out that well for that one submarine. anyways the benifit of uhmwpe fuselage components is simply the fact that you are not constantly fighting the trade off of making the parts as large as possible to fit in the same kiln. also cool to think about is the fact that someone in the field could basically do good enough pressure/water tight structural repair in the field with a roll of plastic and a soldering iron/hot pointy thing. try doing that with thermosets... right now the typical field repair for thermoset defects is literally ducktape/100mph tape. i am not 100% sure on if industry is going towards the balistic weaves (~180g/cm?) or if theyre just working with multiply or monolithic. anyways, i think the next 50 years of aviation is going to basically revolve around uhmwpe. we should probably start making it in the US instead of shipping it all over from china lol. the gell forming process was perfected over here so.... globalism. good video
For my uni project, I am assessing an opportunity to use UHMWPE for the pressure pipelines. What would be an approximate cost of production of pipe segments 150 inside diameter 3+ mm thickness? I know it is a long shot but none the less worth asking :) thanks
Hello Ivan - I have no idea on the cost of piping unfortunately, as that would depend on the country of acquisition, the amount of material purchased, the amount of shaping/tool work required beforehand, and any currency exchanges between the country of supply and the destination country. Pick makers tend to buy in quantities unsuitable for long pipe use, so I'm not sure what the equivalent cost would be. Any plastics firm dealing in UHMWPE would likely be able to cost this for you. Sorry I can't be more help!
Yes indeed - I mean damp hands/dry hands. I've spoken to lots of players with different skin types trying to find out what works for these situations. I'll be doing a video more in depth on it soon.
Sup man. Your video here is helping me better understand what im trying to do... Could you tell me. Is there a way to turn styrofoam PE into UHMWPE at home?? Of course im trying to make armor... So hardening is important. I used a sorta thermal cycling process that seemed to harden it. But im no chemist and im way outa me league here. Thanks
Hi - I'm repairing an acoustic guitar for a friend,... he prefers a more 'bassy tone' than a thin/sharp/bright sound. - - The saddle is non-standard in thickness & height,... ( 75mm x 3.5mm x 12mm) and I am contemplating making a saddle from UHMWPE ( or HDPE) to try and provide this 'tonal quality' and fabricate this 'odd' size. - - What would be your thoughts on this as a material - and what would be the availability of a small piece of these materials ??? . .
UHMWPE isn't desperately hard to find, there's a few people supplying it. It's very hard on tools, though I'd imagine you've got the necessity equipment from what you said. Certainly the wear resistance is very high and you can get it in all sorts of colours, which is a plus if you're looking to match things. I've never experienced where making a saddle out of it, but I'd be interested to see how you get on! Send a pickture to the Instagram @heavyrepping 🎸⛏️⛏️
Good lord, mid-shit I lost it. Physically and the phone! The damn phone almost landed on my self lubricity UHMWPE toilet seat and into the pit of despair. Thanks for the laugh at 530 :)
Nice, in depth discussion on UHMWPE! I tend to just say polyethylene or PE, for short. UHMWPE is rarely my first recommendation for tone. I usually recommend it for ERG, and guys who love super heavy gauge strings. Harder materials tend to suffer them like they're being hit with a hacksaw, but UHMWPE just takes the punishment! It's great for recording, as it has a very even, smooth response, and less of the scratch and chirp you get from harder materials.
I want to learn more about Riki Le Plectrier's "Hardgum". It comes in 3 hardnesses, and I have no idea what it is. If you search "Hardgum" on Google, the only result is from Riki Le Plectrier.
I've found a couple of these sorts of materials, one was a strange graphite compound used by Xufoy, and the other is the Ibanez Elastomer. Wedgie do rubber picks but they disintegrate as you're playing them.

Excellent in-depth review.
Thanks for the tips about UHMWPE. We are trying to import it from oversea now. It helps me to understand what it is. Good luck!
we can cooperation with you for that.
I didn't realize this was about guitar picks when I clicked on it. I was so confused for a while...
I found this stuff, because I was looking for armor plates.
How do you spell that, Katchem?

Thanks. I was planning to ask them. In any case, your video was super helpful!
Best material for skateboarding skids! 👍🏼
Can you better quantify what you mean by skin type effecting grip?

I should add, tonally speaking it's big and full with a very round quality, so I'd imagine there's an optimum thickness to stop it getting too dark.
Link your first two vids plz?
Here's the whole thing boss:

I want a jazz 3 in this material! Now :D
Check out BHL Picks on Etsy!
Uhmwpe - it feels like bubblegum and sounds like god.

Please tell me any equivalent material of uhmwpe
We are using in structural bearings
Do you mean an alternative to UHMWPE?
@@HeavyRepping
Yes sir,please help me out
Peek
👍👊
You forgot about the purple plectrums micro
