Injectable foam/core

[erikssonniklas]

Hi Everyone

I am looking for injectable PU or PVC (or any other you can recommend) foam which I hope to inject into a 3m long mould. Some key properties I am looking for is:

- Density – somewhere between 35-60 kg/m3
- Short cure time – in the mould
- As low internal mould pressure as possible – I’m hoping to be able to use composite moulds
- Low shrinkage when cured
- Temp/fire/sound properties not prior

This method if possible will save me a lot of time, when I don’t have to mill each divinycell block by hand.

Thankful for any comment.

Are you asking about something like Z-Plex?

They are making a large hovercraft out of it.

Thanks kach22i, but no.

I'm hoping to pre-cast the foam core before i laminate around it.

look on my links Page http://newboatbuilders.com/pages/links.html About half way down on the left side it says flotation foam. A lot of these guys also supply other types of foam.
