LG Chemical NBR 6280 High Acrylonitrile Polymer
Categories:	Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)
Material Notes:	Description: NBR 6280 is a copolymer of butadiene and acrylonitrile manufactured by advanced emulsion polymerization technology of Goodyear and LG Chem. NBR 6280 is a non staining, high mooney, and medium high acrylonitrile polymer designed to aid in processing operations such as extruding and calendaring. NBR 6280 has been designed to satisfy the need for high level plasticizers. Applications: NBR 6280 is recommended to use in shoe products, chemically blown sponge, resistance to fuel and oil products. CAS No: 9003-18-3 Information provided by LG Chemical
