Over the 20 years that Tim Freeman (Managing Director, Freeman Technology) has been working with powders, significant advances have been made in powder testing technology and in the efficiency of powder processing. These advances come from a more developed and secure understanding of powders and how to control their performance.
The discussions with those in industry tend to focus around the following key themes:
- Why isn’t my powder (process) performing well?
- How can I identify the right powder for my application?
- What testing technology will optimally support my activities?
This whitepaper collates a series of posts which appeared on LinkedIn that address these questions, from the standpoint of current knowledge and good practice. Beginning with material that summarises what we now understand about powders, focusing on powder flowability, a critical parameter for many processes.
Several other areas are also covered:
- Exploring the impact of particle, size, shape and humidity
- Reviewing the traditional powder testing toolkit (including tapped density and shear testing)
- Reproducible powder testing
- Powder characterisation techniques for:
- Hopper design
- Capsule filling
- Dry powder inhalers
- Segregation
- Tableting
- Wet granulation techniques
- Powder characterisation techniques for:
- Formulators
- Process designers and engineers
- Equipment manufacturers
- Quality control

About us
Freeman Technology specialises in systems for measuring the flow properties of powders and has nearly 20 years' experience in powder flow and powder characterisation.
The company invests significantly in R&D and applications development, and provides detailed know-how to support its range of products. Expert teams guide and support users around the world in addressing their individual powder challenges, focusing on delivering the most relevant information for the process. The result is world-leading solutions for understanding powder behaviour - in development, formulation, scale-up, processing, quality control, or anywhere that powders have a role.
Freeman Technology’s solutions include the FT4 Powder Rheometer®, a uniquely universal powder tester, and the Uniaxial Powder Tester, a complementary tool for quick and robust powder assessment. Systems are installed around the world in the chemical, pharmaceutical, toners, foods, powder coatings, metals, ceramics, cosmetics, and many other industries. They deliver data that maximise process and product understanding, accelerating R&D and formulation towards successful commercialisation, and supporting the long term optimisation of powder processes.
Founded in 1989 as a developer of automated testing systems for materials characterisation, the company has focused exclusively on powders since the late 1990s and in 2018 became part of Micromeritics Instrument Corporation. The company’s R&D, manufacturing and commercial headquarters are in Gloucestershire, UK, with operations and distribution partners in key global territories. In 2007 the company received the Queen’s Award for Enterprise in Innovation and in 2012 the Queen’s Award for Enterprise in International Trade.
