What vinyl do you mean if it's not the stuff records are/were made of?

 I'm talking about the vinyl you use when you sew. I don't know what it is.
Ah, there's several types but it's some form of cloth with a plastic (PVC) coating bonded to it. This gives general information about vinyl fabrics (because they make 'em):

But it is plastic-coated cloth in simple terms.

PVC fabric doesn't have to be PVC-coated cloth.  It can be straight-up sheets of plasticized-PVC. Like the pictures I've attached below.

I will admit the seams are not sewn.  They were formed with heat, pressure, or possibly chemical action.  Some sort of "dark magic" for sure.  You may claim that these artifacts don't really count as true "fabric", or as belonging to the realm of "crafts", since the seam forming process might be difficult to duplicate at home.

BTW, y'all read the scary stuff I posted previously about phthalates and dioxins, right?

Yes, but you heat-weld that stuff rather than sewing it - right?

Yeah, that's what I was saying, "dark magic", um... here:
http://en.wikipedia.org/wiki/Plastic_welding

I already admitted that the techniques used to make the seams maybe put this material outside of the traditional sphere of "sewing" and "crafts". 

So why did I mention it at all?

Because this stuff is pure vinyl (plus plasticizers and dyes).  I think this is the stuff people are talking about when they use the word "vinyl", the pure stuff.

Or maybe not.  It could be that everyone is talking about something different when they use the word "vinyl", which makes the word not all that useful, certainly not specific.

Anyway I think this pure vinyl, like they make beach balls and shower curtains out of, is a material that doesn't really work well with a needle and thread.  Hence the desire to bond it to actual cloth, so that you get a composite material that's slippery and waterproof, and can also be sewn with needle and thread

Maybe that's what you were saying, with the link to spradlingvinyl.
Well I asked what they meant and they said sew-able, so I was going from that.

Do you  mean Naugahyde? The fabric backed vinyl plastic,  simulated leather stuff.
I'm pretty sure Naugahyde is made from nauga skins. That what I heard from my uncle, and he's a nerf herder.
;-)
Ah, therein lies the problem. You see, naugas are now extinct, the result of overambitious nauga hunters and trappers. Currently, nauga pelts are harvested from the cloned hides peeled from the carcasses of the last two known living naugas.
There is hope that one day scientists will be able clone living, breeding naugas by implanting nauga DNA into unicorn egg cells, eventually producing enough viable naugas to release them back into the wild.
You can also make nauga skins into pleather. Stop me if you've seen this one already:

Vinyl is another word for PVC, polyvinyl chloride.  Vinyl = PVC.  It's the same stuff. It's one of the world's most popular and widely produced plastics.

I am guessing that you are asking about vinyl in the context of fabric and clothing, since this question was categorized under "Craft", and also listed with tags, "craft" and "sewing".

You said "NOT vinyl records", but it turns out that vinyl clothing and vinyl records are all made from PVC (as are credit cards, insulation on wires, shower curtains, PVC plumbing pipes, etc), even though the mechanical properties of the old LP records and vinyl raincoats are very different.  The records are flat and rigid, yet the raincoat is floppy and flexible.   The reason this is possible is through the magic of plasticizers.  Like the name implies, plasticizers make PVC more soft and flexible.  The PVC raincoat fabric is more flexible than a LP record because it has a lot more plasticizers in it.

The plasticizer story is not complete without mentioning phthalates, and the legend of these being endocrine disruptors.

The PVC story is not complete without mentioning both the plasticizer legends, and also dioxins, which are rumored to show up upon burning PVC in air.

You can discover these various stories via the Wiki article on PVC.

But the one about decomposing plasticizers turning Barbie's skin green... that one you'll find here:

Oh, uh, almost forgot.  PVC-based "pleather" (plastic leather) is sold as "cruelty free" because its manufacture doesn't involve killing animals, like traditional leather does. Not all pleathers are PVC based.


This is what it is chemically.  You can follow the trail from there.
