Tear resistance is a complex result of other basic properties, such as modulus and tensile strength. Many laboratory methods have…

Resilience is defined as the ratio of energy given up in recovery from deformation to the energy required to produce the deformation, usually expressed as a percentage. Hysteresis is the percentage of energy loss per cycle of deformation of 100% minus the resilience percentage.
At Molded Dimensions Group, we know it’s not always easy to pick an elastomer—there are many factors to take into…
Friction of urethane polymers against non-lubricated surfaces decreases with increasing hardness of the polymer, as shown in Figure 1. Because…
The electrical properties of elastomers that are most commonly measured are: Resistivity Dielectric Strength Dielectric Constant Power Factor Materials suitable…
Hardness, as applied to elastomers, is defined as the relative resistance of a surface to indention by an indenter of…
When subjected to load, all elastomers exhibit an increasing deformation with time, known as creep. This occurs at any stress level and takes place in compression, tension, and shear loadings.
The following cost comparison shows the ratio of prices for selected materials to the lowest cost elastomers: EPDM, SBR, and…
Compression set tests, described in ASTM D-395, are of two main types: Method A, compression set under constant load; and…
The shelf life of molded parts assumes storage in controlled environmental conditions, both in terms of temperature and humidity. The…
