Ozone reduces the useful life of all materials except for which of the following?

Ozone is known to have damaging effects on various materials, primarily due to its strong oxidizing properties. It can cause degradation in materials such as rubber, wood, and most plastics, leading to reduced durability and useful life.

Nylon, on the other hand, exhibits a relatively better resistance to ozone. While nylon can undergo some changes when exposed to ozone over extended periods, it does not experience the same level of degradation as rubber, wood, or plastic. This resilience stems from nylon’s chemical structure, which is less reactive to ozone. Thus, when considering the materials listed, nylon stands out as the one that is relatively unaffected by ozone, making it the correct answer in this context.
