Rheology & Viscosity Made Easy

Rheology is often viewed as something of a ‘black art’ whereas, if understood well, it can provide tangible data to achieve desired performance. Clarity around the core fundamentals enables efficient management of the rheological properties of your product. Join this online rheology training and:

1. Get a grip on rheology by linking more easily desired performance (pourability, sag resistance...) to the corresponding rheology properties


2. Get ready for confident result interpretation by bringing G*, G', G'', tan delta values out of abstract shadow with simple, real-life phenomena association


3. Ease your viscosity adjustments by clarifying the impact of imposed shear, shear history and temperature on your formulation

Formulators, QC managers & technicians and Process developers with a need to get more familiar with rheology basics and principles.

The following sections will be covered during this session:

1. Introduction
   • What is rheology?
   • What are structured fluids and viscoelastic materials?


2. The Rheologist’s Toolkit of Parameters: Identifying the information critical to your products and processes
   • Structure Parameters:
     1. Phase Angle
     2. Complex Modulus
     3. Elastic and Viscous Moduli
     4. Compliance
     5. Zero-shear Viscosity
   • Yield / Recovery Parameters:
     1. Yield Stress
     2. Yield Strain
     3. Thixotropic Breakdown Rate
     4. Thixotropic Recovery Rate
   • Flow Parameters:
     1. Viscosity at Relevant Shear Rate
     2. Infinite Shear Viscosity
     3. Viscosity-profile Parameters


3. Understanding viscoelasticity and the concept of elasticity in liquids
   • Definition of "solidity" / elasticity
   • How to measure "solidity": the oscillation technique
   • Viscoelastic parameters explained
     1. Comparing food products: Hotdog mustard vs cream cheese
     2. Comparing topical products of varying “stiffness”: Ointment, lotion & cream
     3. Viscoelasticity and timescale


4. Back to the Rheologist’s Toolkit: what have we learnt?


5. 30 mins QnA - directly answered by the expert


6. For more questions, email us up to 3 days from the course

The concepts will be presented in an accessible style, without the fearsome equations that often dominate the published literature on the subject.
