The ultimate in lightweight fillers for epoxy and polyester resins. Produced from a plastic material, the density of these microballoons is even lower that the glass microballoons, but the price will reflect the savings in weight. Much easier to tool the cured surface than glass as well. If you want the best and lightest, go phenolic.
