Chemical Match-Up Guide The following chart helps to determine the average suitability of various materials for use with specific chemicals. It shows the corrosion effect chemicals have on different materials. It does, however, not consider the permeability of the materials or the variable conditions which can influence the product performance on actual job applications. Such conditions include chemical concentration, temperature and combinations, and the length of time the product is in contact with the chemical. In addition, products of the same material but of different thickness may perform differently on the same job.
