At non metalic materials microorganisms decompose organic natural materials or similar structure with natural. At sintetic materials with a structure similar with natural the MIC appear. At maromolecular MIC do not affect the polimer because are inert but attack the plastifiant. read more

Plastics contain many of the same kinds of atoms as other objects. But in plastics, these atoms are linked to one another in more complicated ways.
