Our versatile 3:1 thin-wall heat shrinkable tubing is also available with an Adhesive, "dual-wall" construction. Dual-wall is made by combining two different materials. The outer wall is Polyolefin heat shrink, and the inner wall is a hot melt adhesive. When exposed to heat (usually a bit lower than the activation temperature of normal heat shrink), the inner layer begins to flow, just like hot melt glue. When the tubing shrinks and cools down, this inner layer forms an adhesion layer between the tubing and the component or wire. This provides a water-tight seal, protecting the connector and/or wire. It also allows the tubing to stick to the substrate, thus the name “adhesive-lined” heat shrink tubing. Use Polyolefin Heat Shrink Tubing for industrial applications, cable repair, intricate electronics protection, and anywhere you need a versatile seal to insulate and secure electrical components. Practical uses for heat shrink include Wire Insulation, Wire Identification, Wire Bundling, Mechanical Protection, Color Coding, Lightweight Harnessing, Strain Relief, and Solder Insulation.
