Dual Wall PTFE FEP Heat Shrinkable Tubing is constructed with an exterior jacket of Heat Shrinkable PTFE and an inner liner of Extruded FEP. Dual Shrink PTFE FEP is designed for use in areas of high temperature, and takes advantage of an FEP inner liner that melts during shrink down. The FEP melt liner creates a seal not available with other Fluoropolymers. When shrinking, the FEP melts and flows while the heat shrink PTFE compresses and contains the material forming a solid mechanical encapsulation.

Dual Wall PTFE FEP or Dual Shrink is designed to provide a tight, moisture-proof bond over wires, cables, connectors, splices, terminals. Dual Wall material can also be used as an end cap for wires.
