Sorry but carpet is not an insulator. As to static it's actually a GENERATOR.
When the fibers rub together carpets create brand new static which travels into other things.
Any one that has ever walked across a carpet and gotten zapped by a door knob has experienced it for themselves.
I once had a client that made the mistake of having his offices carpeted with short-shag carpet.
Anytime someone walked across the room and plugged in a USB stick the static discharge fried the USB chip on the motherboard.
They had over a dozen systems with dead USB ports before they called me.

Actually, polyester is an insulator. That's why a charge can build up when you walk across a carpet.
POLYester is just a plastic. Only some plastics with additives can block static current. I don't think that is one of them.
In regards to static, no it isn't an insulator. It's a generator and a conductor.
A real insulator has to insulate (block current) in all directions, not just through the middle.
Static Current and Dynamic Current are not the same. Static travels on the surface, not through the middle.
Anything that will Generate static can also conduct it - making it a Conductor by definition.
Materials that will generate static behave like an insulator clad with a Static conductor, yet it is one material.
It's unfortunate (and problematic) that they never came up with a word for that. Least that I know of.

If you look closely the photographer appears to be naked other than goat leggings.
Be that as it may, I'm not buying demonic explanations or witchcraft.
The plastic in that doll will not conduct dynamic current (could not use it as a conductor to power a bulb with a battery)
Clearly the static charge is getting from the fancy generator to the doll's hair. The only path is by way of the plastic.
Thus the plastic is conducting Static. - Not insulating Static. Not blocking Static. Conducting.

There is also the grade school science class thing where you rub one end of a glass, PVC or acrylic rod and pick up paper with the static at the opposite end of the rod. For the charge to get from one end to the other it has to travel the length, so glass, acrylic and PVC are conductors to static.

Now back to the OP's board.
There are none of the required industry markings on that sheet of plastic to indicate it is anti-static.
