Abstract
Polymeric composite materials, particularly highly filled polyurethane composite materials are described herein. Such highly filled polyurethane composite materials may be formed by reaction and extrusion of one or more polyols, one or more di- or poly-isocyanates, and from about 45 to about 85 weight percent of inorganic filler such as fly ash. Certain polyols, including plant-based polyols can be used. Certain composite materials also contain chain extenders and/or crosslinkers. The polyurethane composite material may also contain fibers such as chopped or axial fibers which further provide good mechanical properties to the composite material. Shaped articles containing the polyurethane composite material have been found to have good mechanical properties, such that the shaped articles are suitable for building applications.
