Chemical resistance
Our mono-block probe is made from PEEC
(poly ether ether Ketone), whose chemical
resistance is summarised in the table §9.
WARNING:
PEEC is not resistant to high
concentrations of oxidative acids (nitric and
sulphuric acid > 70 %, etc.) In the case of
probe 8398.5, one must consider the other
materials in contact with the process (EPDM or
VITON gaskets, PP or 316
stainless steel
extension, etc.).
Mechanical
resistance
PEEC possesses a flexion temperature
(pressure: 18 bars) of approximately 300 °C.
In the case of probe 8398.5, take account of
extensions, if any.
Heat resistance
PEEC is a polymer that is particularly well-
suited to sterilisation, it can therefore withstand
temperatures of 140 °C.
