Which of the following is an example of elastomer fabric?

Neoprene is considered an elastomer fabric because it possesses elastic properties, allowing it to stretch and return to its original shape. This flexibility makes neoprene an excellent material for applications where durability, water resistance, and comfort are important, such as in protective gear and diving suits.

In contrast, polyester, Nomex, and vinyl are not classified as elastomer fabrics. Polyester is a synthetic fabric known for its strength and resistance to shrinking, Nomex is a flame-resistant material commonly used in firefighting gear, and vinyl is a type of plastic used for a variety of purposes, including sheeting and coatings. None of these materials provide the unique combination of elasticity and resilience that characterizes elastomer fabrics like neoprene.
