Definition: Nonsubmergible refers to a material that cannot be submigrated or submerged under water. It is typically used in the context of materials for which no mechanical or physical properties are suitable for being submerged, such as metals and ceramics. Nonsubmersible materials are important for applications requiring high strength, durability, or resistance to corrosion. Examples include glass, porcelain, and ceramic tiles, as well as some types of plastics and rubber.
