This chart shows materials rated on their compatibility with chemicals in a letter grading system. The grades for this chemical compatibility guide are as shown below.
A = Excellent - recommended for use
B = Good - Minimal Effect - minor discoloration and/or corrosion
C = Fair - Moderate Effect - swelling may occur, not recommended
D = Poor - Serious Effect - not recommended for any use
N/A = Information Not Available
Temperature Rating System
Some letter grades shown in this chemical compatibility chart may be accompanied by a number for example "A1". The number indicates that the material is rated up to a higher temperature.
Letter ratings without number (A, B, C, D) are rated between at least 18°C (64°F) and 23°C (73°F)
Letter ratings with numbers (A1, B1, C1, D1) are rated to at least 48°C (120°F)
Please note these are the temperatures that the materials have been rated at and are not representative of the material's minimum or maximum operating temperatures.
