Which property is characteristic of synthetic rubber?

The characteristic of synthetic rubber is that it is made from man-made elastomers. Synthetic rubber is produced through the polymerization of various monomers, often derived from petroleum or other chemical processes. This synthetic manufacturing allows for a wide variety of rubbers tailored for specific applications based on desired properties such as temperature resistance, tensile strength, and flexibility.

Unlike natural rubber, which is derived from the latex of rubber trees, synthetic rubber offers a controlled and uniform composition. This enables manufacturers to create materials with properties that can be optimized for particular needs, unlike natural rubber, which may have variability due to its biological origins.

While synthetic rubber does undergo vulcanization, the process typically involves higher temperatures and the use of additives to achieve the desired characteristics, which does not align with the description of vulcanization at lower temperatures. Furthermore, while synthetic rubber can be designed to have excellent elasticity, it does not universally have better elasticity than natural rubber, as both types can have varying elastic properties depending on the formulation and intended use.
