Abstract

A fluoropolymer composition, containing one or more fluoropolymers, is used in a polyurethane composition to facilitate extrusion of the polyurethane composition. The addition of the fluoropolymer composition to the polyurethane composition typically results in less build up in an extruder than would be produced without the fluoropolymer composition.
