Destructive processes, plastics mechanical

While the destruction of plastics by microorganisms is a process based mainly on the chemical effects of metabolites, higher organisms typically cause mechanical destruction. These different damage types have to be taken into consideration, because they can be the reasons for the failure of individual products or entire... 

In the processing of plastic masses the destruction is traditionally considered as a negative factor deteriorating physical and mechanical properties of products and manufacturers try to avoid it in every possible way. Mechanical destruction of molten polymers takes place, primarily, under the action of shear strains effectuating the tension of macromolecules 65-661 in this case, molecules with a high molecular mass...
