Application area

Very well suited for use in:

Almost all acids (hydrochloric and nitric acid), almost all bases (sodium hydroxide, potassium hydroxide), aggressive media such as alkalis, ozone (+40 °C, 200 pphm) and oxygen, polar organic solvents (e.g. acetic acid), oxidizing media (e.g. peracetic acid).

Should not be used in:

Alkali metals such as natrium, potassium or gaseous fluorine at high pressures and temperatures; applications where rubber-elastic properties of an elastomer are required.
