Transponder RF380T
The housing of the heat-resistant data storage unit is made of polyphenylene sulfide (PPS).
The chemical resistance of the data storage unit is excellent. No solvent is known that can
dissolve the plastic at temperatures below 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 excellent resistance to all fuel types including methanol is a particular
characteristic. The following table provides an overview of the chemicals investigated.
