Dual Wall Heat Shrink Tubing is mainly used to encapsulate/protect components from moisture, air or aggressive media.
The Dual Wall Heat Shrink design consists of an outer PTFE tube which is then lined with a melt fusible FEP tube. FEPs melt temperature is much lower than PTFEs shrink temperature so as heat is applied the FEP softens and flows over the component; the PTFE tube then shrinks down onto the FEP. Following the cooling phase, the FEP sets and is firmly bonded to both the PTFE and the component thus creating a strong, moisture tight encapsulation. Maximum working temperature for encapsulated parts is approximately 210°C (410°F).
Dual Wall Heat Shrink Tubing applications include wire & cable harnesses, connectors, splices and any electrical termination where moisture or corrosive fluids can have a damaging effect.
