@PhysicsAstronomyUofU I apologize for the confusion. Unfortunately, we received the thermally reactive tape from Panasonic for the purpose of the demo.
Very interesting. Could you provide more information on the thermal reactive tape used in the video?
can I use this as a cpu thermal paste?
that perfect for mofet on the motherboard copper strip stuck on to a PGS and zigzag the xtra PGS to remove the heat like rods or fins
@digikey Does the pyrolitic graphite sheet also exhibit the weak levitation effect over neodymium magnets as normal pyrolitic graphite peices do?
you mentioned a decent tensile strength is available with this product..... what is the average tensile strength?
What is the part number for the Fluke TI32? I cannot find it on your website.
Stop reading lmao
or... fabs... cursor phenome logic persnickety cloaking.
It sounds like you would be wanting a thermal blanket that insulates rather than conducts heat. Shielding heat would require an insulation layer to cover or mask the elevated temp.
The datasheet says 400°C, NOT Fahrenheit. The max temperature in Fahrenheit is 752°
Also, in your first test, is it really a fair comparison? I'm betting the copper strip has a greater heat capacity than the graphite strip, so, of course the graphite strip transmits heat faster and cools down faster. A more informative test would be to heat two identical thermal masses, such as two cubes of solid copper, and then attach the copper strip to one, and the graphite strip to the other and monitor both for how fast the copper cubes cool down (i.e. how well does each conduct heat away from the copper cubes and dissipate it.)
In other words, your tests gave me little information about how well the graphite sheets function as a heatsink.
His test is actually quite good. It will transfer heat very efficient. It just replaces thermal paste.
@@neutronpcxt372 where can I buy this ? What is the name on amazon ? Is it save to use between cpu die and ihs?
You can't buy this on Amazon.
1. You use it between the CPU cooler and IHS, not silicon die and IHS.
2. You can use it between the die and IHS. However, you do have to cut and exactly apply it to the area of the chip.
3. Buy it here:
www.digikey.com/products/en/fans-thermal-management/thermal-pads-sheets/218?k=&pkeyword=&pv567=1267&sf=0&FV=fffc000a%2Cffe000da%2Cffecfdc9&quantity=&ColumnSort=0&page=1&pageSize=25
Always look for Soft PGS, not PGS.
The reason for not putting it is that alone, under the IHS, unlike between the IHS and the heatsink, is that there isn't a lot of mounting pressure, and there may be a big airgaps, meaning a lot of heat
However, if you put liquid metal on the die, and soft PGS on the inner side of the IHS, or even any other excellent thermal paste, you get absolutely outstanding thermal performance actually!
TLDR: 1. Put in between IHS and heatsink, since there is a lot of mounting pressure.
2. Do not put soft PGS between IHS and die because of low mounting pressure.
3. For absolute best performance possible, but liquid metal and soft PGS between the IHS and the die.
Old comment but listen, graphite/graphene has a much better thermal capacity than that of copper relative to thickness. This test was indeed helpful.
I got some of this material the Digikey # P14965-ND THERM PAD 180MMX115MM W/ADH GRAY 0.0008" (0.020mm) The thinner the carbon pad the better the transfer vertically if you read the specs. I used it as a cpu thermal transfer on a Intel 9600K in place of thermal compound. It is easy to cut since it has a removable mylar backing. With the mylar removed it holds together and has a slight adhesive so it stays in place. You can peel it off to reposition if you need to. I could not see any difference in the cpu temperatures after application. One sheet is 4.5" X 8" so you can do a good number of cpu's with one sheet.
Thermal paste better?
More suitable in passive cooling like smartphone
@PhysicsAstronomyUofU both Steve Spangler and Educational Innovations have Color/White thermochromic paper. I see that bulk suppliers of thermochromic ink are listing orange/red or orange/magenta inks. Maybe you could track them down and wheedle a small sample for making your own paper.
might be CTI thermochromic ink, their website shows $50 for a 1lb sample of offset printers ink of various color-change.
This is great. I want to test graphene for use in an invention I am trying to build.

@MrEngtech Our apologizes, but Digi-Key does not sell the Fluke TI32 at this time.
@MrAwsome514 It looks like a cool experiment but we haven't tested that scenario out, yet.
i stumbled upon this video. seams interesting. what could you use this for?

Does one side adhesive type of pgs insulate heat or insulate electricity. Because in the data sheet it is mentioned only as insulation but what kind of insulation.
Damn he's nervous ASF ha?! XD. But it's a great TIM, far better than IC graphite consumer shit!
That thermally reactive tape is not easy to find. Can you point me toward where I can source some?
Do you need the tape?
@@thermalinterfacematerialsm2755 of course!
GO TO ALIEXPRESS YOU WILL FIND IT VERY CHEAP
@@shafiq936 its chinese ;)
Is the PGS product electrically resistive or conductive?
This foil is made of CARBON? Looks very metallic. Grey, flexible, shiny substance. Good conductivity. Very high melting point. Caarbon relly con be considered as metalloid, especially when selenium is classified s it.
Is it any good to overcome overheating on phone
No wonder phones of 2020 and 2021 cools down fast!
Could you let us know the part number on this material?
Very Best regards,
diveflyfish
Can I use for a phone cooling or a laptop?
Any luck?
I thing yes, but not in the same way we use thermal paste. I want to mod my laptop covering the interior case and connecting my heatsink and others thermal pads (Panasonic PGS too) to a layer of this (my inferior interior laptop peace is made of aluminium. This material is superb for spread temp.
Cut me a piece for the cpu )))
i'm here for a material science assignment
Will this hover magnets ?
computer heat sink anyone?
Nice Slides.Thanks for sharing useful information.SLV industries is well known Graphite Sintering Plates manufacturers in bangalore.
Now..use smartphone
Does this resist corrosion?
"smoldering or... fire"
The word you're looking for is commonly referred to as "burning".
I think difference in thermal mass has a lot more to do with the cooling rate than anything else. Apart from that, why does it matter?
Great, I needed a heat shield for my 1957 Chevy !
:o)
Is it better to attach an aluminum heatsink ( with lower w/m-k of course ) or to leave it this way ?
I wonder if this is the stuff Stanford is using for their Aluminum Graphite batteries
Could you cool grow lights and still get the light required with out the heat omitted by the lights
@tommythan171 how is digikey a copy of kipkay. That's like saying the name Pete is copying Peter.
in Theory: Could this be used to compose a suit witch would defeat Thermal Imaging.
So cool and practically informative. Thank you!
what glasses are those ? ive been needing something like that
mommy can i have a female astrobody!
It is so fu..ing. simple to DIY.
played with this some and will float in a strtong mag field
sinetic wave dispurtion.
Good bye thermal paste
great product. Do you manufacture this?
interesting way to make an ad.
you copy kipKAY NAME!!
No safety gloves ?
Eh What ? Did a search on the digi key site and no product was matched
screw it.. element 14 has it listed
