Material Notes:
Description: NBR 6250 is a copolymer of butadiene and acrylonitrile manufactured by advanced emulsion polymerization technology of Goodyear and LG Chem. NBR 6250 is a non staining, medium mooney, and medium high acrylonitrile polymer designed to aid in processing operations such as extruding and calendaring. NBR 6250 is a low temperature polymerized polymer, and such as, retains the excellent physical and processing properties of a cold nitrile rubber. NBR 6250 is a high mooney version of NBR 6240. Applications: NBR 6250 is recommended to use in packings, shoe products, chemically blown sponge, oil field products, industrial and automotive molded parts.CAS No: 9003-18-3Information provided by LG Chemical
