Chemical Resistance – Material

KEY:

  • S = Superior Resistance/Completely Unaffected under all Conditions
  • L = Limited Resistance, Some Chemical Attack May Occur Over Time
  • M = Moderate Resistance, Superficial Effects only, Testing Recommended
  • U = Unsatisfactory, Severe/Chemical Attack in a relatively short time
  • = No Data Available
