Model : EKT-2100RCR

EKT-2100RCR Rubber Capillary Rheometer is manufactured according to ASTM D5099 specifications to approximate Extrusion and injection (Injection) rubber processing to measure the flow and vulcanization characteristics of unvulcanized compounds, and these material properties Data is useful for process quality control and formulation development in rubber mills.

Whether it is molding, extrusion, or injection processing, the flow and vulcanization characteristics of the rubber will affect the integrity of the appearance of the finished product, and the factors related to the fluidity are the molecular weight size of the rubber material, molecular weight distribution, etc. Type and amount of filler, content and type of plasticizer or softener.... Therefore, by using this simple operation and short test time capillary rheometer, the difference in the flow characteristics of different formulations can be known in the shortest time, which can be used as an effective reference for formula design changes. Of course, for compounds with the same formulation composition but different production batches, good quality control can also be obtained by testing this equipment before entering the production line in order to avoid finding defects in the finished product only after it is put into production.
