Abstract
A recyclable polyurethane foam is produced by reacting a carbon dioxide-based polyol-containing composition and an isocyanate composition. The polyurethane foam may include a molar ratio of active hydrogen to isocyanate groups of 1:0.9. The polyurethane foam may include a catalyst at about greater than or equal to about 0.5 to less than or equal to about 1.5 parts by weight percent.
Claims20
A polyurethane foam produced by reacting a polyol-containing composition and an isocyanate composition, wherein the polyol-containing composition comprises a carbon dioxide-based polyol (CO2-polyol) having a molar ratio of active hydrogen to isocyanate groups of 1:0.9.
A polyurethane foam produced by reacting a polyol-containing composition and an isocyanate composition, wherein the polyol-containing composition comprises a CO2-polyol comprising a catalyst at greater than or equal to about 0.5 parts by weight percent to less than or equal to about 1.5 parts by weight percent.
A polyurethane foam produced by reacting a polyol-containing composition and an isocyanate composition, wherein the polyol-containing composition comprises a CO2-polyol comprising a catalyst at about 1.5 parts by weight percent.
