Description

NBR 2255 is a copolymer of butadiene and acrylonitrile to be manufactured by cold emulsion polymerization through the advanced technology and process of LG Chem.

NBR 2255 is a non staining, medium mooney, and low acrylonitrile polymer designed to aid in processing operations such as extrusion and press molding. And also, this grade offers excellent flexibility and elasticityin low temperature by the minimized block structure and low acrylonitrile content on polymer chain.
