The Instron line of CEAST Rheology systems are used to measure the rheological properties of thermoplastics to characterize the polymer melt flow behavior in the process conditions. This is achieved through a broad range of rheology systems - from Melt Flow Testers to Capillary Rheometers.
These bench top capillary rheometers are suitable for both Quality Control and Research & Development laboratories. Their two-column main frame construction guarantees maximum performance. With a velocity ratio of 1:500,000 corresponding to a piston speed of 0.0024 to 1200 mm/min, they perform tests with unlimited steps at constant shear rate or constant speed. Meets ISO, ASTM and equivalent standards.
Melt Flow Testers
The Instron® MFi Series of melt flow index testers are specifically designed for easy and accurate measuring of melt flow rate (MFR) and melt volume rate (MVR) according to Melt Flow Rate testing procedures determined by ASTM D1238 and ISO 1133 standards.
