Latex of acrylonitrile butadiene copolymer (NBR latex)Nipol NBR latices are available in medium nitrile, medium-high nitrile, and high nitrile, according to the relative concentration of acrylonitrile. We also have modified types, such as modified carboxyl, and non-modified types. Major applications are detailed in tables 4-2 to 4-5, while table 4-6
lists other typical uses, and are useful
references for selecting a specific latex.Table 4-1 Paper processing and fiber treatment(impregnated and internal)
