Personal computer control system
Sophisticated, highly efficient data processing capabilities are provided through the operation in the Windows® environment.


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 and 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.


Features

Wide range selection of extruding pressure
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 the 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 40C to 400C. 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 900 in both sides to ensure ease of die replacement and cylinder cleaning.

Touch panel type LCO screen (Stand-alone system)
The operation is easily done on the LCD screen of a touch panel system.

Operation in Windows® environments (Computer control system)
Data processing is carried out quite easily in the Windows® environments.
