All Things Flow Plastics are amazing materials with the unique ability to ow when heated to relatively low temperatures. They can be formed into a wide variety of shapes and tailored for many different applications. However, their ow properties during this process are complex and affected by many parameters. Instron® provides comprehensive and effective testing solutions in plastics applications and industries through the CEAST SmartRHEO Series. This capillary rheometer simulates the process conditions, measuring the plastic materials ow behavior that characterizes the rheology of...

Plastics are found in virtually every facet of human activity and industry. They are used in everything from plastic containers to new textiles and cutting- edge technologies. There would be no innovation or new applications without determining the performance of plastic materials. Typically, plastics contain two or more polymers plus various additives and fillers. This improves the material processability, thermal stability, and mechanical resistance, while strongly affect the flow properties. This complex behavior of molten plastics, the way they deform when forces are applied and their...

Synthesized polymers are normally compounded with other polymers, inorganic particles, and additives. This improves the physical properties such as thermal stability and transparency during the product's life. Accurate measurements of the flow properties are crucial to prevent processing difficulties and to determine the influence of manufacturing industry is in high demand due to their ability to recover their original shape after stretching or deformation. Their complex elasticity properties affect the material response; therefore, it is necessary to study the flow behavior to establish...

It’s All About Processability The CEAST SmartRHEO Series includes the most versatile and technically advanced capillary rheometers. They are used to determine the rheological properties of polymer samples over a wide range of shear rates and testing conditions. Outstanding Advantages Key testing factors for polymer melts include consistent time savings, accurate results, uniform temperatures, and extrusion speeds. The Twin Bore barrel conguration allows for two simultaneous and independent rheological tests with direct comparison of the behavior of two different samples or two lots of the...

Crosshead with independent load cells on each piston Rigid "H" frame for high Interlocked fume extractor Accurate barrel temperature control with 3 heating zones Fume extractor circuit for environmental concerns is based on a barrel, piston, capillary die fitted inside the barrel, pressure gauge, and fon transducer. The sample is loade into the barrel and heated, and then the piston, attached with a force transducer, pushes the material through the capillary die at a specified rate. Above th pressure - the starting point for CEAST SmartRHEO systems are built in accordance with standards for...

Stretching Unit in Testing Conditions t etching ni Laser System for Die Swell Measurements w Die Swell | Material Elasticity After Extrusion The die swell measurement is used for QC purposes as it affects several polymer processes, such as extrusion and blow molding. When a polymer melt is extruded from a die, the cross-section of the extradite is usually bigger than that of the die. This is called die swell and is related to the material’s elasticity. The swelling can be related to processing problems and can generate defects in the nished product. The Die Swell device, equipped with a...

This is done using special dies with a rectangular cross section instead of standard cylindrical capillaries. The Slit Die system is designed to t three additional ush-mounted pressure sensors, which measures the pressure drop inside the die and eliminates the need for entrance pressure corrections (Bagley).

Dies and Other Accessories A variety of capillary dies is available, with a standard flat inlet or a special conical inlet for materials with high filler content or particular flow behaviors. Standard capillary diameters range from 0.25 up to 2 mm and cover a range of shear rates (rangingfrom less than 0.1 to more than 106 1/s), and standard capillary lengths range from 0.25 (zero-length dies) to 40 mm. Custom dies are available upon request. Die reamers for easy and efficient cleaning are available for any capillary diameter, together with Go/No-Go gauges to check the size tolerance. This...
