Nonpermeable

Nonpermeable describes a material or substance that does not allow liquids, gases, or other substances to pass through it. This property is crucial in various applications where containment or separation is required. Impermeability can be due to the dense structure of the material, its chemical composition, or the presence of a protective coating. The term emphasizes the complete blockage of passage, differing from 'semipermeable' which allows some passage, and 'permeable', which allows fluids to pass freely. This characteristic is critical for applications like food packaging, hazardous waste storage, and the creation of airtight or watertight barriers. The degree of nonpermeability can vary depending on the nature of the material and the substance it must block.

Nonpermeable meaning with examples

• The manufacturer used a nonpermeable plastic film to wrap the frozen vegetables, ensuring that moisture couldn't escape, preventing freezer burn, and maintaining the product's freshness and nutritional value during extended storage. This packaging choice was crucial to the food's longevity.
• Construction teams relied on nonpermeable membranes within the foundation to act as a barrier. The membrane prevented water seepage and minimized potential damage from the soil's moisture, crucial for the building's structural integrity and longevity, effectively controlling the basement's climate.
• The scientist carefully designed a nonpermeable container for transporting the sensitive chemical compound, minimizing the risks of spills or exposure during transport. This choice was vital to prevent environmental contamination and any potential health hazards for transport staff or the public.
• In the construction of landfills, nonpermeable clay liners are essential, preventing harmful leachate from contaminating surrounding groundwater. These layers create a critical barrier, safeguarding the environment and preventing the spread of dangerous substances.
• The scuba diver's drysuit utilized a nonpermeable fabric, which kept water from reaching their skin, allowing them to stay warm and dry. This crucial equipment feature enables safe exploration in cold water environments and enables a lengthy dive.
