Chemical Resistance – Polycarbonate

The chemical resistance of a polymer (polycarbonate) describes its ability to maintain mechanical integrity while being exposed to specific chemical environments. Temperature, chemical concentration, state of mechanical stress, and duration of exposure are key variables that influence the ultimate performance of polycarbonate in a particular environment.

Given these many critical variables, the final classification of “suitable for use” is largely dependent upon the application.  The information contained in the following chart can be used only as a guide in assessing the general suitability of polycarbonate for a particular application.  The prospective user must determine, by suitable testing, the correct application of our product in their particular application.

Please consult Fibox directly should you have any questions.   The following environmental resistance ratings are based upon submersion for 48 hours in the reagent listed.  E-Excellent, G-Good, L-Limited, U-Unsatisfactory, and ND-No Data.
