Very small quantities of polyethylene oxide (PEO) with molecular weight of 600,000 exhibit a non-additive effect of increased permeability that is higher in higher compaction energies (19.62 J). Increased permeability has been proven at such small PEO quantities as 0.0365 %-wt., 0.073 %-wt., and 0.1 %-wt. The above mentioned very small PEO quantities result in slightly increased bondability. It is estimated that PEO effect will find application in metal casting at lower melting temperatures.
