Hydrophilic thermal reticulated polyurethane foam useable for creation of a molten metal filter
A hydrophilic, polyurethane foam manufactured from a composition that includes 90 - 110 parts by weight of polyester polyol, 0.9 - 1.1 parts by weight of ester surfactant, 3 - 20 parts by weight of a hydrophilic surfactant, 1.89 - 2.31 parts by weight of a polyurethane catalyst, 0.126 - 0.154 parts by weight of an amine catalyst, 3.348 - 4.092 parts by weight of water, and 46.98 - 57.42 parts by weight of toluene diisocyanate. The polyurethane is capable of absorbing water in a time period of about 5 minutes or less. The polyurethane foam is a precursor to the formation of a molten metal filter.
