The Benefits of Rheology
Solid and soft solid materials encounter a range of
mechanical deformations (stresses and strains) over a wide
variety of environmental conditions in practical daily use. This
is important for nearly every industry, including aerospace,
asphalt. automotive, ceramics, elastomers, electronics,
food, personal care, biomedical. paints and other coatings,
pharmaceuticals, metals, etc. The deformations experienced
can be static or cyclic in nature, and the environments can be
moderate to extreme temperatures, temperature cycling, or
exposure to different liquids such as water or oil.The increasing
demands for high quality, high performing products makes
it vitally important to understand the complex viscoelastic
mechanical properties of these materials to determine and
ensure their suitability for applications, processability, and
end-use performance. The RSA-G2 is the ideal platform for
fully characterizing and understanding complex mechanical
behavior of solids.
The RSA-G2 can be used for the widest range of traditional and
advanced mechanical measurements and applications including:
•
Modulus of Elasticity (E)
