Polymers & Resins
NBR.
NBR is a copolymer of butadiene and acrylonitrile manufactured by advanced cold emulsion polymerization technology developed by Goodyear and LG Chem. It is a non-staining, medium Mooney viscosity polymer with medium-high acrylonitrile content, designed to aid extrusion and calendering operations. It retains the excellent physical and processing properties characteristic of cold nitrile rubber, and is a high Mooney version of NBR Applications: Packings, shoe products, chemically blown sponge, oil field products, industrial and automotive moulded parts.
