Nietporieusnietporieuze

Nietporieusnietporieuze is a Dutch neologism occasionally encountered in technical Dutch to describe a material with extreme non-porosity. The compound word combines nietporieus (non-porous) and nietporieuze (non-porous, adjectival form) to emphasize the absence of pores beyond standard non-porous classifications. It is largely informal and not part of standardized vocabulary.

Definition and usage: The term is used to characterize materials whose porosity is negligible or below measurable thresholds, effectively acting as a barrier to liquids and gases. It is not a formal material designation and is usually encountered in descriptive passages, speculative discussions, or marketing contexts rather than in official specifications.

Properties and measurement: In practice, a nietporieusnietporieuze material would be described as having porosity approaching zero, and extremely low permeability. Verification relies on measurements such as helium leak rate, gas permeability, or porosity tests, though in many industries the exact threshold for 'nietporieusnietporieuze' varies.

Applications and examples: The term is often invoked in discussions of protective coatings, hermetic seals, dense ceramics or glasses, metal and polymer membranes, and other barriers where penetration by liquids or gases must be prevented. In most cases, true zero porosity is unattainable; the label serves as a qualitative indicator of very high densification and barrier performance.
