  • Application Note: Mouthwash
    We used a Brookfield LVDV-III Ultra Rheometer with Rheocalc v3.1 software for automated instrument control and data acquisition. (Note: any standard Brookfield Viscometer or Rheometer would apply.)
  • High Shear Rate Experiments
    Many times experiments at high shear rates are required to characterize materials that undergo. processing such as spraying, milling, coating and lubrication. The ability of a research rheometer to. make measurements in the shear rate regime of 100,000 s-1 is predicated on two factors; 1
  • Droplet Breakup in Sprays and Coatings
    The Capillary Breakup Extensional Rheometer (CaBER (R)) was initially developed at Cambridge Polymer Group under a Small Business Innovation and Research (SBIR) grant. The instrument has since been commercialized in collaboration with Thermo Haake (Germany) and is now the only commercially
  • Squeeze Flow
    The behavior of polymers in extension is useful to study for many different polymer. processes such as blown film extrusion and blow molding. The STRESSTECH and. DYNALYSER rheometers can both be used to measure the rheological behavior of. polymers in squeezing flow, or biaxial extension
  • Using Rheology Measurement as a Predictive Tool for Solder Paste Transfer Efficiency
    Using a cone and plate fixture on a variable speed rheometer, this study will examine the correlation between rheology and print volume and print volume repeatability of the pastes. The goal is to determine if a specific set of viscosity vs. shear strain rate curves can predict the defect rate
  • Magnetorheology
    . Importantly, the yield stress and viscosity of the fluid when in its active state can be controlled very accurately by varying the magnetic field intensity. CPG has recently developed an MR fluid testing apparatus that integrates with a standard shear rheometer.
  • The Use of the MDR 2000 to Resolve a Problem in Injection Molding
    Converting a high-volume compression-molded bonded seal to an injection-molded process requires dramatically different rheological and curing properties of the elastomer formulation. Shear rates are orders of magnitude higher thus excluding typical rheometer and viscometer data. Compound
  • Rheological Characterization of Skim Milk Stabilized with Carrageenan at High Temperatures
    Superpositioning principles were applied twice to model temperature (25 to 125 8C) and concentration. (0.005 to 0.040% w/w) effects on skim milk and carrageenan solutions. Samples were analyzed using a controlled. stress rheometer equipped with a pressurized sealed cell, permitting measurements
