Neoprene is an example of elastomer fabric because it is a type of synthetic rubber that exhibits elastic properties. Elastomers are materials that can stretch significantly and return to their original shape, which is a key characteristic of neoprene. This makes it particularly useful in applications that require flexibility, durability, and resistance to various environmental factors such as chemicals, oils, and temperature changes.

In contrast, polyester, Nomex, and vinyl do not possess the same elastic characteristics as elastomers. Polyester is primarily a fiber used in textiles and lacks the high elasticity found in elastomers. Nomex is a flame-resistant material primarily made from aramid fibers, which provide thermal protection rather than elasticity. Vinyl is a type of plastic that does not have the elastic properties characteristic of elastomeric materials. Thus, neoprene stands out as the correct answer due to its inherent elastic properties and applications that benefit from such characteristics.
