    摘要： Cavities are partially or entirely filled with a polymer foam. A flexible, porous mesh tube is introduced into the cavity. The mesh tube has a volume smaller than that of the cavity and has openings. A foamable liquid mixture is introduced into the mesh tube. Despite the presence of the openings, the foamable liquid mixture does not pass through the openings in the mesh tube. The captured liquid composition then expands. As the composition expands, it flows through the openings in the mesh tube and makes contact with the walls of the cavity. After curing, a polymer foam is obtained which adheres to the cavity walls.

    摘要： A method of reducing the number or size of voids in a polyurethane comprises reacting the formulation components in a container having an inner surface, or having a liner that has an inner surface, that has been modified to reduce the shear forces that normally accompany introduction of such components into a container. This is done by modifying the inner container's or container liner's surface by profiling and/or engraving it, or by including as a liner a mesh. The profiling and/or engraving or mesh serves to alter the formulation's flow dynamics such that the polyurethane has fewer and/or smaller voids, i.e., has a more uniform density, than polyurethanes formed without the modification.
