Wot, like this?

Hi PWSlack,

No, this item which you showed does not return to it's original shape if compressed. I'm looking to fill a void and if it gets too much weight applied it will return to it's original shape.

Thanks

No that product has no elasticity, if you pinch it or put pressure it will not bounce back to its original shape. stays flat

I know there's expandable pretty much anything out there. Check out these guys for example... http://www.pandeng888.com

There's more, there's a big plastic exhibition coming up in Dusseldorf, www.k-online.de and you can check them out for expandable polymers. Not sure about the need for temperature but I'm pretty sure you can trip the reaction with oxygen, though not sure how...

How about a flexable polyurethane foam? They can be ether solvent blown or water blown. They generate some heat with curing but do not require external heating. Check out BASF or Bayer for systems, or you can often find them at companies which supply industrial arts supplies to schools ( if you need just a little ), IASCO comes to mind in the US. There are many other systems houses that you can Google.

Hye...i dont know much about elastomer foam..but i know a little bit.... if u dont want use or generate heat.... maybe u can produce the elastomer foam..by using high pressure with nitrogen or oxigen liquid as blowing agent..at lower temperature for example ambient temperature..but ur machine should be good because u will use high pressure...
