Hydrogenated Nitrile Butadiene Rubber

ARLANXEO's HNBR products, summarized under the Therban® brand, offer excellent properties wherever high temperature and fluid resistance is needed. The polarity of HNBR is directly influenced by the ACN content. Higher ACN increases the polymer's polarity and, therefore, resistance in non-polar...
