200g vinyl, more static?

I think it depends on the time of year and where you live. I have much more static on my vinyl during the winter months, living in the Northeast.

Purity of the vinyl or lack of purity may have some effect, probably does, but please quote something more authoritative than a magazine article if you want me to believe thickness makes a difference. The static charge consists of ionized particles sitting on the surface, not physically bonded to or internal to the polymer. Which is why you can discharge the surface in an instant.

I've been thinking about this interesting question, and it's very possible I am wrong in my analysis. If anyone has more data that pertains to LP thickness and static charge accumulation, please jump in.

Lewm and ips are correct except it is not particles lewm it is electrons.
Vinyl is almost at the bottom of the triboelectric series  https://www.researchgate.net/figure/A-conventional-triboelectric-series-and-an-experimentally-determined-triboelectric-series_fig2_320579184
It loves to hold on to electrons. Additives make up at best 2% of the vinyl mixture and I doubt they change much. As has been noticed humidity makes a big difference. 
The static charge is being created by the friction of the stylus rubbing the groove. In order to stop the record from charging you have to short it out to ground while it is playing. If the record is allowed to remain charged it will draw dust like a magnet as the stuff in dust is high up in the triboelectric series and is positively charged. It will pull dust right into the groove where your stylus can grind it into place, to pop or tick. Dust that is just on the surface of an uncharged record will be picked up by the stylus for you to brush off. The best way to deal with the situation is a conductive sweep arm like this one  https://www.sleevecityusa.com/Antistatic-Record-Cleaning-Arm-p/tac-01.htm
It also takes any incidental dust out of the way. With this and a dust cover your records will stay clean and static free. I rarely have to clean my stylus and I do not have or need a record cleaning machine as I do not buy used records. 
Modern pressings can be just as good even better then those in the past.
With a good record hold down system such as Vacuum or a reflex clamp record weight makes little if any difference. The quality of the vinyl is way more important followed by the quality of the lathe then the master. 
There is certainly a lot of garbage vinyl out there most of it being produced by major companies like Warner. Smaller companies whose reputation depends on their quality do better like QRP, Pallas and MoFi.
In the old days the quality of the pressing of any popular music was a toss up. Sometimes you got a good one, sometimes not. There were no options. Now we have options be it vinyl, CD, SACD or Hi Res downloads. 

Last time I looked, electrons were subatomic "particles".  Otherwise, I still am dubious that the static charge is created by the stylus in the groove.  But I confess I have no conclusive evidence to the contrary except the white paper published years ago by the Shure Corporation in which they say they evaluated that cause and found no evidence for it.  What is weak about their argument is... no data.  Not even a description of how they eliminated stylus friction as a culprit.
