ABSTRACT:
A method and apparatus for forming a chemical composition from two liquid components selected for cross-linking reaction with each other and a product of the method are disclosed, the method including the steps of selecting the components for interaction to form a solid chemical composition product, the components being intimately mixed with an inert blowing agent to avoid altering chemical characteristics of the chemical composition product and to vary density of the product, the mixture being conducted to an application zone through an expansion chamber having internal dimensions selected for achieving substantially complete expansion of the mixture to a substantially relaxed condition as it passes from the expansion chamber. In one embodiment, means are provided for spraying the product onto the application zone. In another embodiment, delay means are provided for causing increased viscosity of the components. Mesh material forms an integral portion of one preferred product. Another product is formed upon a structural member to which the material is applied in regions of different densities.
