Nitrile Butadiene Rubber (NBR) is considered to be the keystone for industrial and automotive rubber products, such as synthetic latex.
NBR is produced in an emulsion polymerization system. Vaisala K-PATENTS® Process Refractometer PR-43-GP is installed in the polymerization vessel to accurately and reliably determine the degree, and the end-point of the polymerization reaction. The refractometer output signal indicates the degree of polymerization.
