The two key ratios are Coefficient of Friction and Coefficient of Thermal Expansion. The first (friction) indicates the force needed to move an elastomer over a given surface versus the total forces pressing on the elastomers and surface. The latter (thermal expansion) shows the ratio of the original length versus the change in length as a result of temperature variation.
