Elastomers are a type of polymer that can stretch and return to their original shape, much like a rubber band. They are known for their flexibility, resilience, and ability to absorb shock, making them ideal for various applications. Common examples of elastomers include natural rubber and synthetic varieties like silicone and polyurethane. These materials are widely used in everyday products, from tires and gaskets to sealants and toys. Their unique properties allow them to withstand extreme temperatures and harsh environments, making them essential in industries such as automotive, aerospace, and healthcare.
