I'll have to look into Microballoons or Q cell. I liked the ash
because it was very cheap (.15 a pound) and I saw increases in tensile
strength. I think a coupling agent is bonding the ash to the epoxy.
As for the weight of the foam, at 170 kg/m^3 the foam seems to perform
close to core-cell. I've seen better performance with the ash and
short carbon fiber filler. If cost was no object I would probably go
for a SAN foam, but this stuff seems to have a pretty good bang for
