Impervious

Impervious describes something or someone that is not affected or influenced by anything, or that does not allow anything to pass through it. It suggests a state of being impenetrable, whether physically or emotionally. It can refer to materials that resist water, chemicals, or other substances, or to people who are resistant to persuasion, criticism, or emotional appeals. The degree of imperviousness can vary; something might be nearly impervious but still susceptible under extreme conditions.
