I know it's used to join rubber, i.e. seals, but that's about it.
EDIT: Just checking out the 15 minute edit time thing.
Also what tools are required to do it?

Just always wanted to know what valcunizing rubber is and how it is done?

It's how us old farts used to repair tubes in tyres. The area on the tube was buffed clean ( either mechanically or chemically )./ The vulcanising patch was then placed over the area concerned. The vulcanising patch was normally attached to a metal "tray" which had some chemicals in it, similar to the sparklers kids shouldn't play with outdoors at night. The patch is then normally held to the tube by a clamp. The "tray" is then lit, which then catches firw. This provides the heat for the patch to permanently bond to the tube.
These days, patches are chemically vulcanised to the tyre or tube. It's not normal glue and bits of rubber we use to repair your tyres with. We don't "stick" patches to the tyres/tubes, a chemical reaction takes place to bond them together. With the better quality stuff, the only way to remove the patch once applied is to grind it off.

All i know is you need heat and sulfur .thats what we learnt at school and thats all i rememeber. how and in what quantities i am at a loss.
look it up on google maybe.
Talking about this reminds me of those old vucanized rubber tyres patches we used to get( loved setting them on fire) PYROMANIAC ALERT!!

vulcanising rubber in layman terms is sticking it to somthing
mostly done with uncured rubber first the steel is preped ie blasted
and without going into names is painted with a gray undercoat paint which bonds to
the steel then a coat of black which bonds to the grey and rubber.
then you need to make a bonding solution out of uncured rubber and toluene
[for natural ,neoprene]etc. give a coat of this solution then the rubber can be applied.
and alfter all of that it gets put in a autoclave and steem cooked under pressure.
once the rubber is cured it is the vulcanised.
but not as easy as it sounds lol
then for curred rubber repeat first 3 steps for best results then use a 2 part glue compound called sc2000 from rema tip top .mix glue apply to preped surface and rubber surface
let it get touch dry then stick together
let me know what you want to do and ill help you out the best i can
had over 12 years ex in rubber factory
hope this helps

OK, didn't realise there was so many different kinds of vulcanising. I was thinking more just joining the corners of your door seals? By the sounds of things, Super Glue is good. Is there a better glue for joining them?
Good info though, just something you don't hear much about anymore these days. That being the case, how is rubber joined these days?
PS: Love how we have peeps from all different sorts of backgrounds on here.

Did do an internet search on it some time back, but it seems like it's a pre-internet type thing, not much good info.

clean up the edges then get a 2 part rubber glue like sc2000 or there is anothe one cant remember what it is called its not 2 part and is yellow very common
put on both surfaces let get tacky then stick together it wont come apart again.
try not to use super glue as sets 2 hard and goes brital

doublin gtr,
your not talking about" bear contact" maybe.
There is another 2 part adhesive called "conti-secur"
I have used conti-secur and sc2000 in conveyor belt repair industry. Also used large vulcanising presses to splice conveyor belts together, this process uses the raw rubber sheets and liquid raw rubber applied between two areas of conveyor belt after much preparation, then large heating plates are applied top and bottom, an air bag put on top then all clamped together, pressure of around 100-120 psi applied to bag and heated to around 150 degrees c, cooked for varying time depending on belt th's then allowed to cool, remove all presses components presto conveyor belt is now one piece. Much the same as the tube patchs of old which use heat and pressure to join the patch to the tube.

Doublin, sounds like kitchen laminate glue or contact adhesive ---> yellow glue. Apply to both surfaces, let it tack up for about 5 minutes, then push together.

any of those should work fine just make shore surface is clean and also
ruffed up with emry paper or the likes if you have some methal benzine [toluene]
wipe over with that first hope this helps.
racean that liqiud rubber is what i was talking about and with the heated metal plates
it efectively becomes a press. this is how bushes etc are made.
a mold is placed between 2 heated plates and pressed mold heats up in turn curing
