• About Freeman Technology
    Freeman Technology specialise in providing instruments for the measurement of powder
    flow properties and other behavioural characteristics of powders. With over 15 years’
    experience dedicated to powder characterisation we have developed a
    class leading technology and an unrivalled application understanding.
  • The FT4 Powder Rheometer®
    Our customers are those in formulation, process development, commercial manufacture, QA/QC and
    technical services, across industries as diverse as pharmaceutical, chemical, ceramics, toners, food, powder
    coatings, additive manufacturing and many more. If you work with powders, either in a research or production
    capacity, the FT4 is likely to provide valuable information about the flow properties and other behavioural characteristics
    of your materials that is simply not available from other technologies. Click here to view our customer testimonials.
  • Why are powders complex?
    Powders are blends of solids, liquids and gases, usually air, and their flow properties
    may be affected by perhaps 30 or more factors. These include particle characteristics
    such as size, shape and surface properties, environmental factors such as air content,
    temperature and vibration, and chemical interactions leading to adhesion and caking.
  • Why is powder behaviour difficult to predict?
    There is no single measureable parameter that defines how a powder will flow, mix,
    feed, granulate, fill, convey, compress or behave in any other process operation.
    The approach taken in the design of the FT4 is to simulate, as closely as possible on
    the instrument, the environment that the powder experiences in the process or
    application and to measure its response to those conditions.
