What are some examples of non-porous surfaces?

A:

Quick Answer

Non-porous surfaces include glass, processed metals, leather and plastics, and they are further divided into rough and smooth surfaces. Non-porous smooth surfaces include glass and painted or varnished surfaces. Non-porous rough surfaces include textured surfaces like vinyl and leather.

Full Answer

Examples of porous surfaces include cardboard, paper and untreated wood. Porosity is defined by the spaces within the material's surface. Glass, plastics and processed metals are produced by melting the basic ingredients and then cooling them down, creating a uniform surface with no cavities. Porosity affects certain industries; for example, rock porosity is needed when drilling an oil well due to economic reasons. In latent fingerprint recovery, the surface porosity dictates which method is used to retrieve the fingerprint. A non-porous surface is processed immediately, because the print is on the surface and becomes distorted during travel.

    What are the properties of thermoplastics?

    A:

    Thermoplastics are a subset of plastics that can be re-shaped with the application of pressure and heat multiple times. Different types of thermoplastics have additional properties that make them especially well-suited to different jobs, but all thermoplastics share the same characteristic of flexibility when exposed to heat and force.
