Abstract
Talc is combined with polyurethane to facilitate crystallization of a polyurethane composition, particularly a polyester-based polyurethane composition. The addition of talc can allow for more rapid formation of products by, for example, injection molding, compression molding, extrusion, and film formation techniques.
