The document traces the historical evolution of gaskets from their primitive origins in 1820, made from iron filings and sulfur, through key innovations such as the vulcanization of rubber in 1850, which enabled heat-resistant seals. It highlights the widespread but hazardous use of asbestos throughout the 20th century, which led to health crises and subsequent regulation, forcing the development of safer non-asbestos materials using aramid fibers and polymers. The summary concludes by examining modern gasket manufacturing, which employs diverse materials for various industries, and looks toward future applications in extreme environments like space and deep-sea exploration.
