NBR 2860 is a copolymer of butadiene and acrylonitrile to be manufactured by cold emulsion polymerization technology of Goodyear and LG Chem.

NBR 2860 is a non staining, medium mooney, and medium low acrylonitrile polymer designed to aid in processing operations such as extrusion and press molding. And also, this grade offers excellent flexibility and elasticity in low temperature by the minimized block structure and low acrylonitrile content on polymer chain.

This material data has been provided by LG Chem.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
