Analysis of viscoelasticity

Viscoelasticity analysis allows us to characterize the mechanical behavior of a material with both elastic (solid) and viscous (fluid) properties. This study is essential for understanding the response of a product subjected to dynamic or oscillatory constraints, particularly in the cosmetics, polymers, flexible materials, animal nutrition and food industries.

Performed using a rheometer in oscillatory mode, the analysis allows the measurement of key parameters such as elastic modulus (G'), viscous modulus (G''), phase angle (δ) or yield strength. This data allows the optimization of texture, stability, sensoriality or even the performance in use of the finished product.

Commonly analyzed matrices include: gels, creams, pastes, molten polymers, extruded products, flexible adhesives, foams, etc.

At YesWeLab, we collaborate with a carefully selected network of laboratories, most of which are certified and/or accredited (ISO 17025, COFRAC, etc.). These laboratories are chosen based on your specific needs, the matrices to be analyzed, and the required analytical techniques or methods.
