4.8.2.5 Polyamide 6.6 GF (PA 6.6 GF)
The following table provides an overview of the chemical resistance of the transponder made
of polyamide 6.6 GF. Different values may apply to the stainless steel bolt head. 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.
