Understanding powder behaviour

Powder handling presents a variety of challenges, with a number of properties that can impact the ability to accurately and repeatably get a powder into a container, whether that be an inhaler, syringe, capsule or something else entirely!

Many of these relate to physical properties of the particles, including particle:

  • Size
  • Shape
  • Porosity
  • Surface Texture
  • Surface Area
  • Density
  • Hygroscopicity
  • Friability
  • Cohesion & Adhesion
  • Potential for Electrostatic Charge

These properties on a particle level all impact overall powder behavior, including flowability, cohesion, adhesion, compressibility, permeability and electrostatic charging.

Every powder has it’s own unique set of properties which impact handling requirements and dosing performance. The best way to understand these requirements is through physical testing.

The Value of Powder Testing

3P offers powder handling trials to help customers find the most effective dispensing solution for their formulation. A good understanding of powder behavior is an essential foundation for optimizing production processes, developing a high quality product and ensuring a consistent end result. Our experts are ready to help you find the most effective technology to dose your powder, and get your product to market as quickly as possible with viable scale up options for the future.

Dosing Technologies
