4.7.2.4 Polyamide 6.6 (PA 6.6)
The following table provides an overview of the chemical resistance of the transponder made
of polyamide 6.6 (PA 6.6). It must be emphasized that the plastic housing is extremely
resistant to chemicals in automobiles (e.g.: oil, grease, diesel fuel, gasoline, ...) which are not
listed separately.
