4.7 Chemical resistance of the readers and transponders

Explanation of the rating

Polyphenylene sulfide (PPS)

The following table provides an overview of the chemical resistance of the transponder made

of polyphenylene sulfide (PPS). The transponder has special chemical resistance to

solutions up to a temperature of 200 °C. A reduction in the mechanical properties has been

observed in aqueous solutions of hydrochloric acid (HCl) and nitric acid (HNO3) at 80 °C.

The plastic housings are resistant to all types of fuel including methanol.
