Dual Wall / Adhesive Lined Heat Shrink Tubing

Description
The Jdd -MSBG dual wall adhesive heat shrinkable tube is made of a high quality polymer on the outer layer, and a hot melt adhesive on the inner layer. When the heat shrinkable tubing is exposed to a heat source, the inner layer will begin to melt and flow. When the dual wall tubing cools, the inner layer will then form an adhesion layer between the tubing and the component or wire.

Applications
This particular variety of heat shrinkable tubing offers an outstanding environmental protection for a variety of electronic wiring components, including wire splices, wire and cable bundles, and harness breakouts in automotive, truck and marine cables and other industrial fields.
