Thermoplastic materials are known for their elasticity and flexibility, which allow them to be molded and reshaped repeatedly without undergoing any significant chemical change. This property is particularly advantageous in various applications, including robotics, where components may need to be adjusted or reconfigured. Thermoplastics can be softened upon heating and solidified upon cooling, making them versatile for manufacturing processes such as 3D printing and injection molding. Their ability to maintain structural integrity while still being pliable makes them suitable for various dynamic applications, where resilience and adaptability are required.

While other properties like high thermal resistance and tensile strength can exist in specific thermoplastic types, they are not universally characteristic of all thermoplastics. Brittleness is generally associated with other types of materials and is not a common property of flexible thermoplastics. Therefore, the correct understanding of thermoplastics highlights their elasticity and flexibility as defining features.
