Chemical Compatibility of Polymers

  • Eric Skidmore
Lessons Learned

In many industries, metals, such as carbon steel, stainless steel, nickel-base alloys and other alloys, are often used for primary process equipment, such as tanks, piping, valves, and pumps. However, most facilities and equipment cannot practically be made solely from metals because of either cost or functional considerations. Polymeric materials (plastics, elastomers, composites, etc.) are therefore commonly employed to handle chemicals, whether for bulk storage and transfer (tanks, piping, hoses, and tubing), sealing (gaskets, O-rings, and valve seats), corrosion protection (coatings, tank linings, and secondary containment), labware, safety equipment, and many other applications.

However, every polymer is not resistant to all chemicals or even to a single chemical in all concentrations or at all temperatures. Even Teflon®PTFE (polytetrafluoroethylene), an extremely inert fluoropolymer, can be affected by some chemicals. Polymers are susceptible to many possible degradation...
