What Does Polymer Solvent Attack Mean?
A polymer solvent attack is a degradation process that dissolves a polymer's molecular bonds when a solvent is introduced to a material. A polymer solvent attack makes it easier for polymeric materials to corrode.
Corrosionpedia Explains Polymer Solvent Attack
As with most solvents, a polymer solvent is able to dissolve a material's chemical bonds over time, thereby causing a gradual breakdown of certain compounds. Because a polymer has a molecular structure built up mainly or entirely from a large number of similar units bonded together, the damage can be reduced by limiting the material's exposure time to the solvent.
