We provide rheology profiling services a variety of rheometers including a DHR2 as shown Rheology Profiling and Characterization Services

Rheological profiles offer powerful insights into the processing, storage, handling and performance properties of a wide range of liquids and semisolids. The commonly-measured properties include:

  • Viscosity: The resistance to flow of your product across a range of conditions
  • Yield stress: The stress necessary to initiate flow of your product
  • Thixotropy: The rate and extent of breakdown on shearing and recovery at rest
  • Viscoelasticity: Storage modulus and loss modulus, tan delta and normal stresses
  • Creep tests: Creep and recovery for zero-shear viscosity and compliance measurements

Tribology and Bio-Tribology: Lubrication and Friction Testing

Tribology is an exciting, relatively new method for the food, cosmetics and pharmaceuticals industry. Tribology involves taking measurements of the lubricating qualities of products in contact with a range of soft surfaces to predict the interactions of materials with biological structures such as the skin, mucous membranes, tongue or palate. We have also developed methods to consider the impact of salivary proteins such as mucin on lubrication in the oral cavity.

A torsion test attachment for the DHR rheometer. Dynamic Mechanical Analysis (DMA) Service

Dynamic Mechanical Analysis (DMA) is a subset of thermal analysis techniques for characterising viscoelastic properties as a function of temperature or frequency. DMA can explore properties such as the glass transition, damping properties, relaxation properties and decomposition under specific environmental conditions or phase changes such as melt, curing or crystallisation.
