Measurement of changes of state

The state changes – melting, solidification, crystallization, polymerization, glass transition, hardening, gelation, emulsification – play a central role in the formulation, processing and final performance industrial materials and products.

At Rheonis, we offer services of measurement and analysis of phase transitions and physicochemical transformations, adapted to industrial realities and the specific challenges of your processes.

Why measure state changes?

Matter transitions determine:

  • La stability and lifespan products (food, pharmaceutical, cosmetic, specialty chemicals)

  • La implementation of industrial processes (melting, molding, extrusion, granulation, polymerization, drying)

  • The usage properties (texture, strength, elasticity, cohesion, shine, adhesion)

  • La environmental robustness (resistance to variations in temperature, humidity, storage)

Understanding and quantifying state changes is anticipate the real behavior of materials and secure their industrial transformation.
