Material Notes:
Description: NBR 6850 is a copolymer of butadiene and acrylonitrile manufactured by advanced emulsion polymerization technology of Goodyear and LG Chem. NBR 6850 is a non staining, medium mooney, and medium high acrylonitrile polymer designed for easy processing, high productivity and excellent elastic properties. NBR 6850 offers very low mold fouling, fast cure, and high resilience. NBR 6850 is a high mooney version of NBR 6840.Applications: NBR 6850 is recommended to use in wide range of general purpose applications including injection molded o-rings, calendared belting, extruded hose and sponge.CAS No: 9003-18-3Information provided by LG Chemical
