PTFE and Teflon Chemical Compatibility
What Chemicals are Compatible with PTFE and Teflon®*?
- PTFE is the most versatile plastic in terms of chemical compatibility
- Highly resistant to most acids, alcohols, detergents and solvents
- Ideal for use with reactive and corrosive chemicals
- The melting point of PTFE1 is 600°K (327°C / 620°F)
- Low temperature: maintains high strength, toughness and self-lubrication as low as 5°K (-268°C /-450°F) and good flexibility at 194°K (-79°C / -110°F)
- NOT compatible with certain alkali metals and fluorinating agents such as xenon difluoride and cobalt(III) fluoride
PTFE Chemical Compatibility Chart: Polytetrafluoroethylene is very non-reactive and ideal for use with most chemicals. Review the chemical compatibility of Teflon® and PTFE with various chemicals, solvents, alcohols and other products in the cart below.
Please Note: The information in this chart has been supplied by reputable sources and is to be used ONLY as a guide in selecting equipment for appropriate chemical compatibility. Many factors can affect the chemical resistance of a given plastic product, and it is your responsibility to do a test under your own conditions to ensure that the product you are using is fully compatible with your usage. The information in this chemical compatibility chart is offered solely for your consideration and is not a guarantee of results.
Ratings of chemical behavior listed in this chart apply at a 48-hr exposure period. We have no knowledge of possible effects beyond this period. We do not warrant (neither express nor implied) that the information in this chart is accurate or complete or that any material is suitable for any purpose.
