Thermo-Plastic Elastomers and synthetic rubber can be tested on a CEAST SmartRHEO capillary rheometer to ensure adherence to ISO 11443 and ASTM D3835.
When materials like feedstock for Metal Injection Molding do not need to be cured and can be injection molded without extra aids, they can undergo capillary rheometer tests.
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.
Low viscosity fluid with a high-shear environment for spray application can be tested with an Instron CEAST SR20 capillary rheometer.
Testing with CEAST Capillary Rheometers and Visual RHEO Software allows manufacturers to understand the change in polymer viscosity related to time.
With a capillary rheometer, Instron's Die Swell Tester can determine the extrudate swell from the polymeric material placed into a die during plastics manufacturing.
Along with temperature, shear rate, shear stress, filler content, and molecular weight change the fluidity of plastic melts and should be tested for their impact.
To ensure sports goggles have correct visual, mechanical, and thermal properties, check the injection of mold plastic components with a CEAST SmartRHEO machine.
ISO 11443 and ASTM D3835 are specifications for determining the flow properties of polymeric materials at temperatures lower and higher than the melting point.
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.
A capillary rheometer, like the CEAST SR20, can find the flow characteristics of compounded thermoplastic elastomers used in the production of tires.
