Virgin PTFE:
(PFA/TFE) Chemically inert, virtually impervious.
Very few chemicals are known to chemically react with PTFE;
molten alkali metals, turbulent liquid or gaseous fluorine and
a few fluoro-chemicals such as chlorine trifluoride or oxygen
difluoride which readily liberate free fluorine at elevated temp.

Maximum and Minimum Temperatures are the limits for which these materials can be operated.
Temperatures coupled with pressure affect the longevity of diaphragm pump components. Maxi-
mum life should not be expected at the extreme limits of the temperature ranges.
Metals:
Alloy C:
Equal to ASTM494 CW-12M-1 specification for nickel and nickel alloy.
Stainless Steel:
Equal to or exceeding ASTM specification A743 CF-8M for corrosion
resistant iron chromium, iron chromium nickel and nickel based alloy castings for
general applications. Commonly referred to as 316 Stainless Steel in the pump industry.
