Chemicals that affect RF Tags are shown below.
Polybutylene terephthalate (PBT) resin is used for case material and epoxy resin for filling material.
Refer to the following lists and do not use chemicals that affect PBT and epoxy resins.
RF Tags cannot be used in applications with explosion-proof specifications.
 Chemicals That Cause Deformations, Cracks, Etc.
Acetone, trichloroethylene, ethylene dichloride, sodium
hydroxide, and other alkaline substances
 Chemicals That May Cause Discoloration, Swelling, Etc.
Hydrochloric acid (10% RT), acetic acid (5% RT), benzene
 Chemicals that Do Not Affect PPS Resin or Epoxy Resin
Nitric acid (30% RT), concentrated hydrochloric acid, acetic
acid, ethyl acetate (100% RT), potassium permaganate (5%
RH), ethyl acetate, carbon tetrachloride, methanol, ethanol,
gasoline
The above results are from tests conducted at room temperature (23°C). Even if the chemicals do not affect the PPS or
epoxy resins at room temperature, they may affect the resins at higher or lower temperatures. Check the chemicals
carefully in advance.
