What is the term for materials that are constructed to not absorb liquids because they have no pores?

The correct term for materials that are constructed to not absorb liquids because they have no pores is "nonporous." Nonporous materials possess a smooth surface that doesn’t allow liquids to be absorbed, making them ideal for various applications, including sanitation and infection control in barbering. This characteristic ensures that no bacteria or pathogens can penetrate the material, which is vital for maintaining hygiene in a barbershop environment.

In contrast, porous materials contain tiny openings or pores that can trap liquids, making them susceptible to absorption of moisture and potential contaminants. Nonabsorbent refers to materials that do not soak up liquids; however, it is a broader term that may not inherently address the absence of pores. Absorbent specifically refers to materials that can take in liquids, which does not apply in this context. Thus, understanding the unique properties of nonporous materials highlights their significance in infection control practices.
