Typical paint shop applications, such as those used in vehicle
construction, can be realized with these products. Typically, the time at
the temperatures of 220 °C (428 °F) is not more than one hour.
To read or write to a tag, the tag temperature must be less than 85 °C
(185 °F).
Chemical Resistance
The housing material of the data carrier consists of Ryton R-4 (PPS
Polyphenylene Sulphide) which is known to perform well even at
elevated temperature. PPS is resistant to various chemicals.
The following table provides an alphabetical list of chemicals along with
our recommendations regarding their compatibility with Ryton PPS
compounds.
The Data column indicates the amount of data upon which each
recommendation was based. “Extensive” indicates extensive, long-term
test data on the compatibility of Ryton PPS with those chemicals.
“Limited” indicates limited short-term test data on the compatibility of
Ryton PPS with those chemicals. “None” indicates that there is no
actual test data on the compatibility of Ryton PPS with those chemicals.
The recommendations for “None” are based on the knowledge of the
compatibility of Ryton PPS compounds with similar chemicals. The
criteria for “Acceptable” compatibility ratings are the expectation that
Ryton PPS compounds would retain at least 50% of original mechanical
strength. The “Acceptable” compatibility ratings exhibit less than 3%
swell after exposure to the chemical for one year at 93 °C (200 °F). We
caution against extensive exposure to some chemicals at elevated
temperatures; however, brief exposure to those chemicals at elevated
temperatures or long-term exposure at near ambient temperatures, can
be acceptable. “Avoid Exposure” recommendations that are listed for
chemicals with extensive data indicate that we do not recommend using
Ryton PPS in service with those chemicals except under the limitations
cited.
