High Performance Rheometer(Air Bearing)
The Rheometer is specially used to measure the rheological properties of polymer melt, polymer solution, suspension, lotion, paint, ink and food. It is divided into rotary rheometer, capillary rheometer, torque rheometer, and interface rheometer.
The RHM-20 rheometer, same as the HAAK rheometer, TA rheometer, Antonpah rheometer, and Brookfile rheometer, can be used as window to observe the internal structure of polymer materials. Through the response of different scale molecular chains in polymer materials such as plastic, rubber, and resin, the molecular weight and molecular weight distribution of polymer materials can be characterized, and the quality inspection and quality control of raw materials, intermediate products, and final products can be quickly, conveniently, and effectively carried out.
Rheological performance measurement serves as a bridge between the molecular weight, molecular weight distribution, branching degree, and processing performance of polymers, providing a direct connection to assist users in raw material inspection, processing process design, and predicting product performance.
