Abstract
A polyurethane foam produced from a formulation comprising a polyol, an isocyanate, a strut reinforcing agent and a VOC reducing agent. The isocyanate reacts with the polyol to produce the polyurethane foam. By including the strut reinforcing and VOC adsorption agents in the formulation during the reaction between the isocyanate and the polyol, the air permeability and firmness of the polyurethane foam are enhanced while the amount of VOCs within and the level of VOCs emitted by the polyurethane foam are reduced relative to a polyurethane foam produced by reacting the isocyanate and the polyol in the absence of the strut reinforcing or VOC reducing agents.
