ABS material has good chemical stability and can resist corrosion from certain types and concentrations of chemical substances. For common chemicals such as acids, bases, salts, etc., the national standard ABS V-type safety helmet is usually not significantly affected by short-term exposure or low concentration environments, and can maintain its structural integrity and protective performance. But if exposed to highly corrosive chemicals such as concentrated sulfuric acid, concentrated nitric acid, etc., or exposed to high concentration chemical environments for a long time, ABS material may be corroded, causing the cap shell to become soft, brittle, and the protective performance to decrease. When working in an environment with chemical risks, it is necessary to understand the properties of the chemicals in advance and choose appropriate protective measures according to the situation. If necessary, specialized chemical resistant safety helmets can be used.
