What characterizes an elastomer?

An elastomer is characterized by its incredible elasticity, allowing it to stretch and then return to its original shape when the deforming force is removed. This unique property arises from the molecular structure of elastomers, which often consists of long chains of polymers that are capable of significant deformation. This capability is crucial in various applications, such as seals, gaskets, and tires, where materials must endure repeated stretching and compressing without permanent deformation.

In contrast to rigid materials, elastomers provide flexibility and can be employed where damping and shock absorption are required. The ability to revert to the original shape after deformation is what fundamentally distinguishes elastomers from other types of materials. This resilience and recovery make elastomers vital in many engineering applications where durability and performance under stress are essential.
