DuPont Co., Wilmington, Del., is working with LRM Industries, LLC of Orlando, Fla., to develop LRM’s Thermoplastic Flowforming (TPF) process for molding long-fiber thermoplastic composites. Up to now, LRM has been used primarily with polyolefins, though DuPont can contribute expertise in engineering thermoplastics. DuPont’s interest is in building and construction markets. LRM is a joint venture of Envirokare Composites Corp., Orlando, and Nova Chemicals Inc., Pittsburgh. It was formed last year to further TPF development and licensing. TPF is a low-pressure, automated process for molding large structural parts of long-fiber reinforced thermoplastic. This three-step process entails compounding, extrusion of a molten slab into the bottom half of a mold in a vertical press, and compression molding. DuPont’s Building Innovations Group is interested in making large seamless parts, such as novel types of building panels that may incorporate arches or doorways.
