Rotman, D

Rhone-Poulenc (RP; Paris) and Ferro (Cleveland) have agreed to jointly evaluate the manufacturing and marketing feasibility of using rare earth sulfides to replace heavy metals in pigments for plastics. The companies expect to produce test quantities of the rare earth pigments by third-quarter 1994 and to decide whether to form a joint venture by the end of the year. The primary focus of the work will be the use of cerium sulfides to replace cadmium-based red pigments. RP developed the technology, including the optimization of the cerium sulfide particle sizes, during the past three years. The company says the pigments can be used with a range of plastics, including polypropylene and polyethylene, and have coloring and physical properties similar to those of cadmium pigments.
