Material Notes:
Description: NBR 3250 is a copolymer of butadiene and acrylonitrile manufactured by cold emulsion polymerization technology of Goodyear Tire and Rubber Company, USA. NBR 3250 is a non staining, medium mooney viscosity, and high acrylonitrile polymer designed to aid in processing operations such as calendaring and extruding for oil and fuel service products. NBR 3250 offers high resistance to fuels, solvents, oils and gas permeation. NBR 3250 is recommended to in industrial and automotive parts such as fuel hoses and packings. NBR 3250 is a low mooney version of NBR 3280.CAS No: 9003-18-3Information provided by LG Chemical
