The characteristic properties exhibited by plastics are the direct result of their unique molecular structure. Plastics are polymers of very high molecular mass. To enhance their properties, they often contain additives, however, the underlying attributes of a plastic material are determined by the polymer. The molecular weight of the base polymer is a fundamental factor in the characteristics of plastic materials. This includes the mechanical, thermal, chemical, and environmental properties of the material, and ultimately the formed part.
Through the polymerization process, polymers - materials of relatively high molecular weight, macromolecules - are produced. Higher molecular weights are associated with longer molecular chains, and this results in a greater level of entanglement. This has important implications, as higher-molecular-weight grades of plastics will have superior mechanical, thermal and chemical resistance properties compared with lower molecular-weight grades of the same material.
