Frequently Asked Questions

What is the most chemically resistant fluoropolymer?
PTFE (Teflon) has the broadest chemical resistance of any fluoropolymer, rated A (Excellent) for 965+ chemicals. FEP is a close second with 899 A-ratings.
What is the difference between PTFE and FEP?
Both have nearly identical chemical resistance. The key difference is processability: FEP can be melt-processed (injection molded, extruded into tubing), while PTFE must be machined or sintered. PTFE handles higher temperatures (260°C vs 200°C).
