PTFE/FEP Dual Wall Heat Shrink Tubing and Sleeving

Heat shrinkable PTFE sleeving with an inner wall of FEP.

The unique properties of Adtech's dual wall heat shrink sleeving lends its utilisation in any application that requires a high working temperature, non-stick surface, high electrical resistance, and chemical resistance.

Heat shrinkable PTFE sleeving with an inner wall of FEP.

Adtech dual wall FIP heat shrink sleeving consists of an outer sleeve of PTFE heat shrink and an integral inner wall of FEP. When the outer sleeve is shrunk down at 300°C, the FEP inner melts and flows over the component underneath.  When cooled the PTFE and FEP form a fused mass encapsulating the component.

If the component uses PTFE or FEP insulated cable (e.g. on a temperature sensing element), the melted FEP will adhere to the cable, thus sealing the component.

Using Adtech dual wall FIP heat shrink sleeving, it is possible to 'pot' components in a pure fluoroplastic and protect them against mechanical and chemical exposure even in immersed conditions. Heat shrinkable PTFE sleeving with an inner wall of PFA is also available to special order for higher temperature applications.
