Abstract: A method of forming foam material is provided, which includes mixing 100 parts by weight of a compound having cyclic carbonate groups and a foaming agent to form a foaming composition, wherein the foaming agent includes 3 to 13 parts by weight of carbamate salt and 15 to 65 parts by weight of amino compound. The foaming composition is heated to 100° C. to 170° C. for decomposing the carbamate salt into CO2 and amino compound, and the amino compound is reacted with the compound having cyclic carbonate groups to form the foam material.
