Anyone else heard of this? Might be something cool to work with.

Seems like the same stuff as the reusable mold agent I've seen people talk about, but in a larger volume.

The mold making materials looks like the same stuff as instamold (in the US and UK) or oyumaru (Japanese product).  The only difference is how the original manufacture packages the stuff.  Your guys seem to do pellets and the other stuff is in sticks.  Having used the instamold and oyumaru I can tell you it is just like hot glue sticks without the adhesives.

Yep, looks exactly like it.
great stuff if you want to create a fast mold of a simple shape, not so much for creating objects.

You can get plastics like that which are rubbery or stiff when cool.  It looks like the stuff linked is the stiffer type, while instamold and oyumaru are rubbery.

I wonder what it would be like to use this stuff instead of clay or plasticine as the temporary side for silicone mold making. Hmmm. Experimenting may be in order.

Doesn't silicone heat up when curing ?

I have used it to "seal" off teared siligum molds.

Depends on the silicone I think.(?) I've used pinkysil and haven't really noticed a heating up of it, could be wrong though, would require a small test. Resin definitely heats up though.

I think you're right. Looks to me like:

Gorilla plastik is very sticky when heated and much harder than  instamold and oyumaru when cold. Its not my choice for molds because demolding is a pain due to the stiffness.
