Elastomers

Definition

Elastomers are a class of polymers characterized by their elastic properties, allowing them to deform under stress and return to their original shape upon removal of the load. This unique ability makes them essential materials in various applications, particularly in soft MEMS and flexible electronics, where flexibility and resilience are critical for performance and durability.
