According to one embodiment, the disclosure provides a foam-based object containing a foam having a density of 30 kg/m 3 or less. The foam contains a base polyol, a filled polyol, and an additive polyol. The foam lacks a chain extender or crosslinker. In another embodiment, the foam has a hardness loss of less than 15% in a hardness loss test. According to another embodiment, the disclosure provides an initial formulation containing a base polyol, a filled polyol, an additive polyol, and a catalyst, but lacking a chain extender or crosslinker. The initial formulation is operable to form a foam having a density of 30 kg/m 3 or less upon reaction with an isocyanate. A fourth embodiment provides a method of forming a foam by combining an isocyanate with such an initial formulation to produce a foam having a density of 30 kg/m 3 or less and lacking a chain extender or crosslinker. |
