Excessive heat. This can be caused by (but not limited to) using too big of a coil for the airflow, setting the coil too close to the insulator, excessively heating the coil when dry burning.
I used this KF v5 clone tank for 1 day from brand new when I noticed a burning plastic taste at 13.5 watts. The coil was set correctly. I didn't dry burn because it was a new coil other than to burn off any gunk from the new coil with a couple pulses.
Without knowing what material is used in the 'clone' for the insulator it's hard to say.
It doesn't appear melted, cracked, shrunk or burnt to me.
Most of the peek KF insulators I've seen are tan ish, but, it takes extreme heat to taste burnt/melting peek. Like you almost have to try to ruin it.
Makes me think it isn't peek, maybe pom, replace with peek.

PEEK (Polyether ether ketone) which is commonly used as an insulator, begins to melt at ~662°F (343°C). That’s quite high for vaping, but dry burning a coil could easily exceed these temperatures. PEEK is a licenced product which comes at a cost. Willing to bet there are a few atomizers out there that look to be using PEEK, but instead are using some sort of plastic to try and save on the cost of manufacturing.
Did you prime the coil/wick/? I'm sure you did, just had to ask. Any chance your mod settings were not locked in? I didn't know that with my mod, when I change the battery, it retains the wattage setting but it's not locked... accidentally went to TC mode at 60 watts (with my little MTL tank that I normally run 14 watts) Noticed it before any damage. I'm very new to building but remember other posts like this... don't remember what the issue turned out to be (not much help I know)
Just did a search but most issues were with the little Kanger tanks that use micro-coils (those are the ones I remembered)

I can't say for sure what exactly happened to your insulator, I was just responding to the limited information available to me at the time. With the new info supplied, I agree with others and suspect the insulator is probably not actually peek, but another material which is more susceptible to heat. It could also be some residual machine oil that you missed when cleaning the tank before use (if you cleaned it before use) that is heating up and causing discoloration and a funky taste.
Depending on the coil, 13w can still produce quite a lot of heat.
But the picture clearly shows the color is tan...
Not saying it's PEEK, but it's tan.
On the SvoeMesto Kayfun V5 the insulator isn't close to the coil. The coil would burn out before you had enough heat to melt the peek insulator.
This! I have vaped what I believe was machine oil before. It can be kind of plastic-tasting. Sometimes machine oil can be tough to remove and boiling does not always do the trick.
But that insulator does look burned as much as I can tell from the blurry pic.
My suggestion is to replace all the insulators in that tank with new ones and try it. But clean the tank thoroughly before you do, by taking every single piece apart, in order to remove any residual chemical/plastic taste that might be left behind from the old, burnt insulator. Otherwise it may prove pointless to even try to resolve this situation.

Be aware that some of those insulators are for the mini version, not the full size V5. FT search does not seem to have the ability to use negative keywords.

Yep primed the wick. My mod stays at 13.5 nothing changes. Juice wick material all stays the same.
There is a hole in the insulator where it shows the brown spot in the divot. Sorry my phone takes crappy photos.
Assuming you are referring to the authentic KF V5...
Here's the deck of the V5 clone in question...
Here's the authentic Kayfun V5...
A Very Likely cause, especially in a Clone, would be an Inferior Material used as an Insulator.
Polyetheretherketone (PEEK) is supposed to be stable for continuous use up to about 450F. And give where the Insulator is in that KF v5, you would need to be some Serious High Temp Vaping or Prolonged Dry Burning to cause problems with a Real PEEK insulator.
englishmick, I didn't know they made tiny alien coils... where can I get some? Maybe the guys in that little spaceship know.
Hard to say what that is without having it here and being able to mess with it. Question: what happens when you brush over the stained area with a wet toothbrush?
