Polymer vs. Elastomer: What's the Difference?
Edited by Huma Saeed || By Sumera Saeed || Updated on October 25, 2023
A polymer is a large molecule composed of repeating subunits, while an elastomer is a type of polymer that can be stretched and return to its original shape without permanent deformation.
Key Differences
Polymers are macromolecules formed by linking together small molecules called monomers. This process of formation is known as polymerization. The versatility and adaptability of polymers make them a fundamental component in a plethora of applications. In contrast, elastomers represent a subset within the polymer category. These specific polymers are known for their elasticity, allowing them to stretch and revert back to their original form.

Elastomers derive their name from the inherent elastic properties they possess. These properties enable elastomers to undergo significant deformation when under stress but recover when the stress is removed. Polymers, on the other hand, can vary in their properties; some might be rigid, while others might be flexible, depending on their chemical composition.

The expansive world of polymers encompasses a range of materials from plastics to fibers to rubbers. Polymers can be natural, like DNA and cellulose, or synthetic, like nylon and polyethylene. Elastomers, residing within the polymer family, include materials like natural rubber, silicone, and certain synthetic rubbers.

An easy analogy to distinguish between a polymer and an elastomer would be to consider the relationship between squares and rectangles in geometry. Just as all squares are rectangles but not all rectangles are squares, all elastomers are polymers, but not all polymers are elastomers.
