Talk:Kapton

message: Added a paragraph about the history of Kapton use in avionics. This is common knowledge among avionics technicians. Maybe someone can find an authoritative reference for this as well. --Miikka Raninen 12:21, 13 April 2006 (UTC)

message: since kapton is a specific type of polyimide.
on the other hand, this article is at least as good, if not better, then the polyimide article, so it could go either way
Also propose merging ultem into polyimide

message: The language is a bit unclear, and leads more to questions than answers. What does: "the only material to ignite insulation blankets" mean? I suppose that kapton is the burnable part of the blanket, but if not I suppose there are more sources of heat to ignite a (what kind of?) blanket. And "dry arc-track at 10,000 °C" - is that good or bad? Are electrical flames hotter with kapton insulation? Or is it a good thing and is kapton resistant up to that temp? 217.19.29.156 (talk) 10:07, 24 January 2010 (UTC)

message: I added a paragraph on kapton use in Apollo. Further details and references would be good!

message: For which reasons is Kapton used in (flexible) printed circuits? --Abdull (talk) 19:13, 19 December 2010 (UTC)
replies: text: because kapton is 
-flexible at the temperature ranges the circuit is normally exposed to, 
-has good dielectric/insulating properties, 
-has good mechanical propeties, and
-is fairly easy to work with in the board manufacturing processes (fab and stuffing)

thread_title:  When was it developed? 

message: I'm confused by the first sentence in this section.
"The thermal conductivity of Kapton at temperatures from 0.5 to 5 kelvin is rather high for such low temperatures, κ = 4.638×10−3 T0.5678 W·m−1·K−1.[3] This, together with its good dielectric qualities and its availability as thin sheets have made it a favorite material in cryogenics, as it provides electrical insulation at low thermal gradients.".
Is Kapton a thermal insulator or a thermal conductor?  The value K = 4.638x10-3 W·m−1·K−1 is a rather small number.  This is less than the thermal conductivity for rubber K= .16 to 0.255 W·m−1·K−1, which definitely a thermal and electrical insulator.
While the thermal conductivity for Kapton at .5 to 5 kelvin might be high for that temperature, is it not still low and still a relative thermal insulator?
Also Kapton is used for electrical insulation of electrical wires.
Most materials that are good or poor electrical conductors are also likewise good or poor thermal conductors, but I suppose not always.   There are also many coatings used on Kapton such as aluminum, etc., that might change the electrical or thermal conductivity or both.  
Or is there a typo in the sentence?  Could it possibly have been intended to say "The thermal conductivity of Kapton at temperatures from 0.5 to 5 kelvin is rather low for such low temperatures" ?  — Preceding unsigned comment added by Mcrodgers2 (talk • contribs) 21:32, 9 July 2019 (UTC)

message: As a non-chemist I can't understand how something with so many double bonds should be so ridiculously stable over such a wide temperature range. I'd assume double bonds/rings would want to break, which after all would be energetically more favourable, but over a range of nearly 700 C they don't...? 78.146.83.112 (talk) 23:13, 10 January 2024 (UTC)
