NBR B6120 Acrylonitrile Butadiene Rubber Description NBR B6120 is a copolymer of butadiene and acrylonitrile manufactured by cold emulsion polymerization technology. NBR B6120 is a non staining, low Mooney viscosity, medium acrylonitrile content designed to improve mold and extrusion flow, and to reduce scorch in highly loaded compounds.
