Planning the RF300 system
4.4 Chemical resistance of the readers and transponders
4.4.2.4
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.
