摘要: A thermoset non-isocyanate polyurethane foam (NIPU) composition includes a reaction product of a polycyclic carbonate, a polyamine; and a foaming ingredient including a carbonate-based chemical blowing agent. The reaction product is configured to form a urethane bond. The polycyclic carbonate and the polyamine can be bio-derived. A process for making the NIPU foam includes the steps of: (a) selecting a polycyclic carbonate and a polyamine; (b) mixing the polycyclic carbonate and the polyamine to form a reactant product including a partially cured gel matrix; (c) adding a foaming ingredient comprising a chemical blowing agent including a carbonate; (d) curing the mixture to form the NIPU foam. The reaction is tunable by changing cure temperature, water content, and/or acid composition.

摘要: A polyurethane foam is disclosed having unique load bearing characteristics rendering it suitable for a variety of applications. The foam exhibits high surface-softness and smoothness properties, making it well-suited for use in articles such as pillows and mattress toppers. However, upon continued application of pressure, the resilience of the foam increases sharply, translating into a remarkable support characteristics that make the foam suitable for use in the seat portions of chairs and sofas, as well as in the base portion of mattresses. The foams therefore address the limitations of conventional, high-resilience and visco-elastic polyurethane foams. A process of making the foam and its use in various articles is also disclosed.

摘要: Foam composites and methods of preparation thereof are discussed. For example, the foam composite may include a polymeric material and a particulate filler, wherein the compressive strength of the foam composite is equal to or greater than 20 psi, the density is 4 pcf to 40 pcf, and wherein the thermal conductivity is equal to or less than 0.050 W/m K. the particulate filler may include fly ash, e.g., in an amount of about of 45% to about 75% by weight with respect to the total weight of the foam composite. The foam composite may be prepared from a mixture of a polyol, an isocyanate, the particulate filler, and a liquid blowing agent having a boiling point equal to or greater than 25° C. or 30° C.
