A capillary rheometer, like the CEAST SR20, can find the flow characteristics of compounded thermoplastic elastomers used in the production of tires.
A CEAST Capillary Rheometer has been used to test the flow behavior of plastic cap liners of bottle cap to prevent leaks with a tight mold and quality seal.
ASTM D1238 prescribes four test procedures to measure the fluidity of plastics in the Melt Flow Index with testing the rate of extrusion of resins through a die.
With a CEAST SR50 Capillary Rheometer, Instron was able to test silicone materials to determine which can undergo extrusion at room temperature, observing ISO 11443.
A controller can test how much a mold will shrink by placing it in a high-pressure chamber with controlled temperature, volume, and pressure, following ISO 17744.
For ISO 22007, testing technicians can determine thermal conductivity data easily by using Capillary Rheometers with applicable accessory.
To test the quality of un-vulcanized rubber, use a CEAST SR20 capillary rheometer to measure its behavior at different temperatures, pressures, and shear rates.
Instead of manual cleaning methods, the Integrated Barrel Cleaning Device is used to easily clean Melt Flow Testers after every test to ensure accuracy.
