PTFE and Teflon Chemical Compatibility Chart
Teflon®* PTFE Chemical Compatibility Chart: Check the chemical compatibility of Teflon® and PTFE with various chemicals, solvents, alcohols and other products.
Polytetrafluoroethylene (PTFE) is very non-reactive and is often used in containers holding reactive and corrosive chemicals. According to DuPont, its melting point is 600 K (327 °C; 620 °F). It maintains high strength, toughness and self-lubrication at low temperatures down to 5 K (-268.15 °C; -450.67 °F), and good flexibility at temperatures above 194 K (-79 °C; -110 °F). Certain alkali metals and fluorinating agents such as xenon difluoride and cobalt(III) fluoride can damage PTFE, but otherwise it is highly resistant.
Please Note: Actual properties may change due to processing method, compound type, extruded dimensions and other variables. It is the user’s responsibility to evaluate and fully test the suitability of the product for their specific application.
