General Chemical Resistance Chart
For Specialized Plastic Materials
Here's a convenient reference chart of chemical resistances of the most commonly used plastics materials for specialized components. These are graded on an A-F scale. Grade A signifies most resistant, and Grade F means the material does not have a good resistance to that type of chemical.
