CFT-EX Series onstant Test Force Extrusion Type Capillary Rheometer Flowtester

Constant Test Force Extrusion Type Capillary Rheometer Flowtester
This device evaluates viscosity properties from the relationship to temperature, pressure, and flow velocity, etc., for flowable materials. It demonstrates its power in research and development, production processes, and quality control for various flowable materials such as thermoplastic resins, thermosetting resins, toner, composite materials, ceramics and rubbers.

Features
Efficient Testing with a Reliable Evaluation Method
High test force precision, provided by a weight-based constant test force loading system, enables high measurement reproducibility and test efficiency. In addition to increased operability to improve testing efficiency, accurate temperature measurement and stable control are provided through a reliable temperature control system.

Evaluation of Softening and Flow Beginning Temperature Using Constant Heating Rate Testing
Testing methods include a constant temperature method a constant heating rate method. The constant heating rate method permits measurement of resin softening temperature and flow beginning temperature to determine shear rate and viscosity at each temperature and cannot be conducted using other capillary type rheometers.

Viscosity Evaluation of Thermosetting Resin
Weight-based constant test force extrusion is used to measure the amount of piston movement (movement speed), which is used to determine viscosity. Highly reproducible measurements of fluidity of thermosetting resins, which cure rapidly due to heating, can be determined due to the highly precise temperature control and the range of test forces available.
