What is a characteristic of soft rubber?

Soft rubber is known for its low durometer rating, which indicates its softness and flexibility. The durometer scale measures the hardness of materials, where lower values signify softer materials. This characteristic makes soft rubber suitable for applications requiring a certain degree of pliability and shock absorption, such as gaskets, seals, and cushioning materials.

The other characteristics listed do not apply to soft rubber. For instance, being fully rigid or used in high-pressure applications does not align with the properties of soft rubber, which is inherently pliable and is not designed for high-stress environments. Additionally, while soft rubber can indeed be cut relatively easily due to its softness, this is not its defining characteristic compared to the significant attribute of its low durometer rating.
