Nichtporös

Nichtporös is a German adjective meaning non-porous. It describes a material that does not contain pores or tiny openings. This characteristic means that liquids, gases, or other substances cannot easily penetrate or be absorbed by the material. Non-porous materials are often smooth and dense. Examples of non-porous materials include glass, many plastics, and polished metals. The non-porous nature of a material is significant in various applications where impermeability is desired, such as in food packaging to prevent spoilage or in medical devices to maintain sterility. Conversely, porous materials, like sponges or certain types of wood, have many small holes that allow substances to pass through. The distinction between porous and non-porous is crucial in material science, engineering, and everyday life for selecting appropriate materials for specific functions.
