Chemical Resistance of URETEK Material*
The resistance of the expanded URETEK polymer to chemical agents has been evaluated as a function of loss of volume following prolonged exposure, and evaluated in the following categories:
- Excellent resistance (loss of volume < 3%)
- Good resistance (between 3% and 6%)
- Fair resistance (between 6% and 15%)
- Poor resistance (between 15% and 25%)
- Not recommended: Only concentrated nitric acid and concentrated sulphuric acid destroy the material upon contact.
