Fluorinated Ethylene Propylene
FEP can be used to make high-temperature heat shrink tubing used for reflow catheter layups. FEP is used for many purposes where sterilization and heat resistance are primary factors. It is very similar to PTFE chemically. It adds on a CF3 pendant group every fourth carbon, which dramatically lowers its crystallinity. Because it is less crystalline than PTFE, its melt temperature is lower, which allows it to be melt-processed. All of its other material properties are nearly identical to those of PTFE.
