VIRTUAL ANALYSIS OF ENVIRONMENTAL EFFECTS
ON ELASTOMERS, POLYMERS & COMPOSITES

What is CheFEM?
CheFEM quantifies effects of environmental exposure on mechanical response and on fugitive emission characteristics. CheFEM is based on fundamental "Chemical" Sanchez-Lacombe Equation of States and "Mechanical" FEM routines. The unique approach allows you to perform quick assessments of different materials and to virtually reformulate polymer chemistry and filler composition.
