Physical measurement of materials and formulations
At Rheonis, we carry out industrial physical measurements to characterize in depth the complex formulations and materials : powders, suspensions, pastes, gels, films, composites, food products, cosmetics, pharmaceuticals and advanced materials.
These measures target the key physical properties which condition the Implementation, stability and performance in use some products.
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)
-
On 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.
