Shimadzu CFT-500D/100D
Efficient Evaluation of Rheological and Thermal Properties
Shimadzu Dynamic Ultra Micro Hardness Tester
The Shimadzu CFT-500D is the industry workhorse instruments for the R&D,  production control, and quality control of plastics, adhesives, rubbers, paints, printing inks, toners for copying machines, foods, cosmetics, and many other materials.
     
  Stand-alone System  
  The operation is quite easily managed on the LCD screen of a touch panel type. Also, an excellent cost-performance ratio is ensured.  
     
  Personal Computer Control System  
  Sophisticated, highly efficient data processing capabilities are provided through the operation in the Windows™ environments.  
     
Features  
  Wide range selection of extruding pressure [0.4903 - 49.03 MPa (5 - 500kgf/cm2) in CFT-500D, 0.098 - 9.807 MPa (1 - 100 kgf/cm2) in CFT-100D]  
  Measurement can be conducted with an extruding pressure like that used in the actual injection molding. 
The CFT-500D and CFT-100D, therefore, provide more practical data than the instruments that use conventional MFR (melt flow rate) method, in which the test pressure is lower than the actual injection molding pressures
 
     
  Test at constant heating rate is possible   
  The CFT-500D and CFT-100D permit tests at a constant heating rate, as well as at a constant sample temperature.
Tests at a constant heating rate make easy the measurement of softening temperatures and flow beginning temperatures of resins which is impossible with capillary rheometers of any other type. Also, the shear rate and viscosity at particular temperatures can be easily measured
 
     
  Accurate flow rate measurement, and reliable data  
  Weights are used for loading to ensure high accuracy in constant-loading tests.
Temperature is one of the most important factors for obtaining reliable data. The CFT-500D and CFT-100D use Shimadzu's original temperature control system, specifically designed for this purpose, which ensures high accuracy and stability in temperature control and measurement.
 
     
  Wide test temperature range  
  The test temperature is adjustable over the range from 40°C to 400°C. This ensures reliable tests of a wide variety of materials, ranging from foods to engineering plastics.
The test temperature range can be further widened through the use of the optional low temperature test attachment and/or higher temperature heating attachment.
 
     
  Easy die replacement and cylinder cleaning  
  The cylinder unit can be swung 90 in both sides to ensure ease of die replacement and cylinder cleaning.  
     
     
Applications
 
  Thermoplastic resins  
  Measurement of melt viscosity of resins provides useful information for determination of molding temperature, pressure, and flow rate.
The CFT-500D and CFT-100D, operating with a shear stress like that used in actual injection molding in production process, provide highly practical data.
It is necessary to measure mean molecular weights and molecular weight distributions in order to evaluate the quality of blended polymers.
The CFT-500D and CFT-100D provide useful data for determining the blending ratios of polymers
 
     
  Thermoplastic resins and adhesives  
  The measurement of hardening rates of thermoplastic resins is rather difficult with any other method. With the CFT-500D or CFT-100D, hardening time can be obtained from the plasticity curves  
     
  Toners for copying machines  
  The melting temperature and viscosity are important factors for obtaining clean clear print in copying machines.
The CFT-500D and CFT-100D permit easy and efficient measurement of such temperature and viscosity
 
     
  Rubbers and Rubber materials  
  Injection molding machines are often used in rubber production. The CFT-500D and CFT-100D, which utilize a mechanism similar to that of ordinary injection molding machines, can provide highly useful data for setting the molding parameters. The data are also used for viscosity control of non-sulfurized rubbers.  
     
  Plasticity of ceramic materials  
  In molding of ceramics, some types of resins, called binders, are added to enhance the plasticity, before they are charged in a mold. The CFT-500D and CFT-100D are used to measure such plasticity to know the best mixing ratio of binders.  
     
  Foods  
  The CFT-500D and CFT-100D are used to select the best components and their best composition ratios, in production of chewing gum, butter, margarine, bread, candy, chocolate, etc  
     
  Cosmetics and medicines  
  The CFT-500D and CFT-100D are used to evaluate physical properties of these materials.  
     
  Paints and inks  
  The CFT-500D and CFT-100D are used for measurement of their plasticity  
     
  Fibers  
  The CFT-500D and CFT-100D are used to select the best melt condition for production of synthetic fibers.
