CFT-EX Series - Applications
Capillary Rheometer Flowtester
Measurement of the melt viscosity of resins facilitates the selection of measurement conditions, such as temperature, pressure and flow rate during molding. The CFT-EX series, which supports measurement at shear stresses similar to those used under actual molding conditions, provides very useful data.
Thermosetting Resins and Adhesives
Measurement of the curing rate of thermosetting resins is difficult using typical physical methods. The CFT-EX series, on the other hand, permits measurement of the curing time from a flow curve.
Copying Machine Toners
Melting temperature and viscosity of toner are key factors to obtaining clear print with copying machines. The CFT-EX series permits simple and efficient measurement of such temperature and viscosity.
Paying close attention to viscosity is critical when conducting press and injection molding of composite materials such as GFRP and CFRP, consisting of reinforced fibers mixed with thermoplastic and thermosetting resins, respectively. The viscosity can be evaluated under various pressure and temperature conditions for injection molding, as well as the matrix (base material) and filler content.
Injection molding machines are typically used in the molding of rubber. Since the mechanism of the CFT-EX series is similar to that used in injection molding machines, very useful data can be obtained, thereby permitting, for example, management of viscosity in unvulcanized rubber.
In the molding of ceramics, resin additives referred to as binders are typically added to the mold to improve fluidity. This fluidity can be measured to determine the optimal proportion of binder to be used.
Foods: Evaluation of compositions of chewing gum, butter, margarine, bread, candy, chocolate, etc. for determining optimal consistencies in the mouth
Paints and Inks: Evaluation of writing characteristics and fluidity of ink used in ballpoint pens and fountain pens, etc.
Fibers: Selection of melt spinning production conditions
