Description

NBR 6230 is a copolymer of butadiene and acrylonitrile manufactured by advanced emulsion polymerization technology of Goodyear and LG Chem.

NBR 6230 is a non staining, low mooney, and medium high acrylonitrile polymer designed to aid in processing operations such as extruding, injection, and calendering.

NBR 6230 is a cold polymerized polymer, and such as, retains the excellent sticky characteristic, good processing, and the good physical properties of a cold nitrile rubber.
