FEP

Applications

Applications where FEP tubing is chosen usually require more clarity, flexibility or a lower heat shrinkable temperature than PTFE. More information on the properties of FEP resin can be found in our Tech Info section.

Advantages of FEP Tubing 

• Lower heat shrink temperature than PTFE
• More flexible than PTFE
• More optically clear than PTFE
• More lubricious than PFA
