Chemical substances not listed
The following sections describe the resistance of the various transponders to specific
substances. If you require information about chemical substances that are not listed, contact
Customer Support.
Polyphenylene sulfide (PPS)
The data memory 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.
