The HAAKE MARS iQ Rheometers are well-suited for the rheological characterization of a broad range of samples from low-viscous or water-like up to stiff and paste-like semisolids:
- Investigation of paints, coatings and inks: shear viscosity, thixotropy, yield stress, shear recovery, levelling and sagging behavior
- Rheology and textural properties of foods and foodstuffs: shear viscosity, yield stress, tribology, texture analysis (axial bending, breaking, squeezing tests), phase transition
- Rheology of cosmetics and pharmaceuticals: viscosity, yield stress, viscoelastic properties, stability tests
- Rheology of polymer (e.g. polymer melts and solutions): viscoelasticity, phase transitions (glass transition, crystallization, melting), processing behavior (hot melt extrusion, molding, spinning), molecular weight, curing
- Rheology of petrochemicals (crude oils, fracking liquids and drilling fluids): viscosity, yield stress, pressure dependent properties, stability tests, wax deposition, wax appearance temperature (WAT)
- Dynamic shear rheometer (DSR) tests according to AASHTO, ASTM and DIN used for bitumen and asphalt
- Construction and building material (cement paste and slurries): flow properties of suspensions with large particles
