What are the advantages to using high performance engineered plastics? Why use them?

High performance engineered plastics are used in applications where metal s do not perform well. Plastics are different from metals in that they are chemical-resistant, microwave clear, non-conductive, and corrosion resistant. For example, acid-resistant plastics can be used in semi-conductor processing machinery and in chemical processing. Certain salt water resistant plastics like Isoplast perform better than metal in boats and submarines.

Microwave clear applications include medical devices, satellites, cell phone antennas, submarines, and test equipment. PEEK, PVDF, PTFE, PVC, and CPVC are commonly used in these applications.
