Material Notes:
Description: NBR 3280 is a copolymer of butadiene and acrylonitrile manufactured by cold emulsion polymerization technology of Goodyear Tire and Rubber Company, USA. NBR 3280 is a non staining, high mooney viscosity, and high acrylonitrile polymer designed to aid in processing operations such as calendaring and extruding for oil and fuel service products. NBR 3280 offers high resistance to fuels, solvents, oils and gas permeation, and also it can be used for economic compound by high loading of plasticizer on compound recipe.Applications: NBR 3280 is recommended to use in industrial and automotive parts such as fuel hoses and packings.CAS No: 9003-18-3Information provided by LG Chemical
