Dental moulding material

Gun Shy

Hi, I know not a Dental issue as such but hope you may allow it, I'm looking for information on the moulding putty that dentists take impressions with. It's for an idea/project I'm working on and I would like to be able to try it out to see if it works.
It's not for anything dental, I'm not attempting to make teeth or anything !!!!!
ie. what type of material is it "silicone " I'm guessing?

So long as its not a medical use only material (or is it ?, although I can't imagine it is) I'm hoping to get my hands on about a matchbox sized amount of material to test to see if it works or not.

Again I'm assuming all this but can someone correct me if I'm wrong

Silicone or silicone type ?
2 part material mix together to make the paste ?
Sets in a few mins
Is there a use by date on the putty (pre mixing of course) ?

Any info appreciated
Thanks

Dental IMpressions materials come in a variety of types and the one you want depends on
1. The level of detail you want to capture.
2. The cost.
3. The stability over time of the impressions.
4. The elasticity of the impression (for undercut objects you want something you can removed without tearing the impression.

Basically there are 4 types:
1. Plasters and hard materials like ZoE - these are usually only for specific situations and I doubt they work for your purpose.
2. Alginate - water mixed with a seaweed derived powder that sets in minutes. Pros: very cheap, easy enough to handle, good detail. Con: not stable need to be poured up quickly, weak if unsupported, multiple pours loose detail,
3. PVS (polyvinylsiloxaine) - silicone. Come in two types addition and condensation. Condensation is cheaper but less accurate (I have a feeling this might be the one for you PM me details of what you want to do and I can recommend). Addition is stable, accurate and rigid. Good elastic properties also. This stuff is expensive.
4. Polyethers - this is way to expensive and very rigid. Probably not necessary for your needs, designed to work better in the absence of moisture control.

Give us some more details, and I can let you know where you would get this stuff, its easy to get and not on prescription of anything.

Looks good but probably not for the op as it would stick to the item that he/she is taking the impression of....
