PTFE FEP Dual Wall Heat Shrink Tube Transparent And Black
The double-wall heat shrinkable tube is mainly used to protect the components from corrosive gas and liquid from outside.
The double-wall heat-shrinkable design includes an outer layer of PTFE tube, and then a fusible FEP tube lining. The melting point of FEP is much lower than the shrinking temperature of PTFE, so when heated, FEP will melt and cover the components first, and then the PTFE tube will shrink and wrap the FEP. After cooling treatment, FEP solidifies and tightly combines with PTFE and components to form a tight protective layer to seal the entrance. The maximum operating temperature of the packaged components is approximately 210°C (410°F).
The application range of double-wall heat shrinkable tubing includes wire and cable harnesses, connectors, joints, and any electrical terminals that may need to be protected from damage by moisture or corrosive liquids.
