Plastics for corrosion‐resistance applications

If corrosion resistance were the sole consideration in specifying materials for components in chemical engineering, then plastics and polymeric substances in general would have even greater application than they have at present. But it is very seldom that corrosion resistance can be considered in isolation from factors such as physical strength and cost, with the result that the widest use of plastics in chemical engineering hitherto has been in the form of coatings or linings for metal units rather than in self‐supporting structures.
