Abstract
A system for producing a foamed isocyanate-based polymer includes a base line comprising a first mixing device operable in a first mode and a second mode and having an active hydrogen-containing compound input and an isocyanate input. A complementary line is provided and includes a second mixing device having a filler material input. In the first mode, the first mixing device receives a feed from the active hydrogen-containing compound input and the isocyanate input, mixes the feed to produce a first foamable polymeric composition, and dispenses the first foamable polymeric composition into a first mold. In the second mold, the first mixing device returns the feed, without mixing, from the active hydrogen-containing compound input and the isocyanate input to the second mixing device which mixes the feed with feed from the filler material input to produce a second foamable polymeric composition, and dispenses the second foamable polymeric composition in a second mold.
