Hi I'm looking for a dense foam which is lightweight which can be machined by hi speed turning which would accept a acrylic lacquer finish,I'm currently using a product called Rohacell but I'm looking for an alternative 

Hi,

We should certainly be able to supply you with such a foam (I guess we're talking model board or tooling block here). Do you know what density foam you're using? - We should have something pretty close.

If you don't know what density you're currently using then I would suggest our PU80 as the minimum starting point for a pattern making foam. You would be able to paint it with a 2k acrylic although the suitability of this depends on how durable and tough you want the finished part to be. PU80 Low Density Model Board is an 80kg/m3 foam which means it really is more of a foam than a board but if does have a lovely fine finish for a foam (much finer than our low or high density foams, which is why we classify it as a modelboard). We have higher densities too, I'm sure our PU 240 Medium Density Model Board would be up to the job but it's a matter of whether you're looking for something this dense or you can manage with a lower density (therefore cheaper) board.

If you can get back to me with some indication on density I'll be able to pick out the right board for you, certainly.

Hi Matt , thanks for replying the foam I'm using at the moment is 71kg/m3 but looking for something a little harder say somewhere around 110kg/m3 .regards Richie

Hi Richie,

OK, well, our 80 would be the closest to what you have and it is a little denser than what you're using. After that we jump up to a 300 (unless you count our High Density Foam which is 90kg but doesn't have such a fine surface finish) so my suggestion would be to see how you get on with the 80.

All the best, Matt

Cheers Matt I will have a look at the pu80 and see how I get on with that, I will see if I can get a sample of each to try out. Cheers Richie
