Temperature:
The lower operating temperature limit is usually set by the metal housing and -29°C is the typical lower working limit, however with the correct supporting materials and design PTFE is perfectly capable of working at cryogenic temperatures-200-260°C. The upper-temperature limit is set by the fluoropolymer, and as mentioned previously not by the “lab” specification, but the strength of the materials at temperature and 260°C is the usual maximum – and even this is quite challenging for the materials. When selecting lined equipment, however, one must think of the maximum and minimum temperatures, the potential for thermal shock and upset conditions.
