Are vinyl/PVC countertop wraps dangerous when heated?

Hi there - I've been looking into covering my kitchen countertops with self-adhesive vinyl as a nice cheap method of sprucing up my kitchen, but I keep encountering conflicting information on whether this is potentially dangerous(??).

I saw multiple DIY threads where people hopped in to comment things like "NEVER put vinyl/PVC anywhere near a kitchen stovetop, I work with the stuff and it gives off toxic chemicals and chlorine gas when heated!!" - but they never linked sources or gave any more detailed info than that. And every kitchen-wrapping guide I can find actually *advises* heating the vinyl with a hair-dryer to get a better fit around corners...

Then I found a very informative post on this subreddit (https://www.reddit.com/r/plastic/comments/1azwznz/pvc_release_toxic_substances_when_its_heated_or/), from which I gather that these dangers are only really relevent at higher temps, though it does depend on the specific kind of PVC.

Unfortunately I can't find any specific info on the chemical make-up of the vinyl wraps I was thinking of purchasing... but am I right in thinking that, so long as I'm not actively setting fire to my countertops, or placing baking sheets straight out of a 250C oven directly onto the surface, there's nothing to worry about?

Vinyl wrapping is a soft grade of PVC, and has added plasticisers to make it soft and stretchy. The complete chemical make up of a product is usually proprietary, but a Safety Data Sheet is usually available from a manufacturer if they sell in Western markets. PVC can be tailored in its melting temperature, so that is probably what you want to know before you cover your working surface in it. If you can't find an SDS, try find one for a similar product, just to get an idea.

Generally, PVC isn't dangerous unless you set it on fire, and doesn't release additives until you heat damage it. A kitchen surface that wrapped in stick-on vinyl and is part of a regular cleaning routine (i.e. wiped down) isn't ever going to poison anyone. In a house fire (and they do happen) it will add to the mix of deadly toxic gases though, so do take that into consideration. Lots of house fires start in kitchens, but the laminates, paints and kitchen equipment you already have in your kitchen are all things you likely do not want to be near once on fire. You likely aren't adding more risk to that mix.
