Chemical resistance of Arnitel®

Arnitel® has very good resistance to automotive greases and oils. This makes Arnitel highly suitable for use in automotive applications in contact with greases and oils at high temperatures such as cable ties, and fuel lines, and hydraulic tubes and hoses.

The chemical resistance of Arnitel increases with the hardness.

Arnitel U shows the best chemical resistance, followed by Arnitel E and Arnitel P.

The soft grades of Arnitel are soluble in halogenated hydrocarbons at room temperature, whereas the harder grades will only dissolve at elevated temperatures.

Arnitel is sensitive to strong acids. This goes especially for Arnitel U. High temperature applications are not suitable if there is continuous contact with acid.
