Description

NBR 2875 is a copolymer of butadiene and acrylonitrile to be manufactured by cold emulsion polymerization through the advanced technology and process of LG Chem.

NBR 2875 is a non staining, high mooney, and medium low acrylonitrile polymer designed to aid in processing operations such as extrusion and press molding. And also, this grade offers good flexibility and elasticity in low temperature by the minimized block structure structure on polymer chain.
