Cel-Span® 844

80% active endothermic foaming agent concentrate, formulated for applications with high gas requirements. Releases carbon dioxide gas upon decomposition. Is safe when used under the conditions of intended use. Upon complete decomposition (activation) of the chemical foaming agent, the extruded and injected parts will become white, a color common to endothermic chemical foaming agents. Recommended for extrusion, and injection and structural molding of any kind of thermoplastics, except polycarbonate and thermoplastic polyesters.
