PTFE (Polytetrafluoroethylene) ASTM D4894, D4895
PTFE is the most commonly used fluoropolymer, has excellent high temperature corrosion resistance to virtually all chemicals except
elemental fluorine and molten alkali metals. In addition, PTFE possesses unusual non-stick properties which can reduce or eliminate the
buildup
of deposits on the pipe or fitting walls.
Service temperatures range from -20°F (-29°C) to 450°F (230°C) - Chemical Resistant Guide
Note: Operating temperature limitations may be encountered depending upon specific chemical environments.
