Ivyland, Pa.-based Mansco Products Inc. has shipped its 200th Torsional Oscillatory Viscometer
(TOV) system for the Chinese market. The TOV continuously measures the viscosity of polymer resin,
fiber and filament processes.
The TOV initially was sold exclusively to DuPont and DuPont Engineered plants, but it has
been available to the general world market since 1999. Mansco offers the TOV in China through
direct sales and a number of original equipment manufacturing companies. The company also has
installed TOVs in several recent projects in India.
