Technical data sheet Dual wall heat shrink tubing

Do you require Dual wall Heat shrink tubing made from PTFE / PFA? Get in touch with us. Larger dimensions on request.

POLYTETRAFLON® Dual wall Heat shrink tubing is specially used in applications, in which the ends have to be closed in a media-tight manner or water-proof joints are necessary.Their functionality consists of one inner and one outer tubing. The outer heat shrink tubing is made from PTFE and is more temperature-resistant than the internal FEP or PFA tubing. When shrinkfitted, the internal tubing liquefies and all the hollows are filled up. The outer tubing shrinks and presses correspondingly.

The standard length of POLYTETRAFLON® Dual wall Heat shrink tubing is 1.22 m. We produce pre-shrunk standard lengths against an additional charge; else we manufacture the tubing in standard lengths that are not pre-shrunk. In the latter case, the inner and outer lengths are loose and movable. Deviating lengths will be available on special request. If you need special lengths less than 50 cm, we recommend that the tubing should be preshrunk.

We also provide PTFE or PFA stoppers for sealing bigger parts. On request, we manufacture from raw materials as per general specifications, e.g. FDA or USP class VI, and also as per customer specifications.
