Product Description

Double Wall Heat Shrink Tube

Crafted with meticulous precision, our Double-wall heat shrink tubing combines the versatile softness of polyolefin with the superior adhesion of hot melt adhesive through co-extrusion. The polyolefin outer layer stands as a guardian, offering unparalleled insulation, halogen-free properties, and flame resistance. Meanwhile, the inner layer of robust hot melt adhesive ensures exceptional mechanical strain relief and airtight sealing. This formidable combination makes it the go-to solution for insulation and protection of wires, cables, and connectors requiring sealing efficiency, waterproofing, and moisture resistance. Perfectly adaptable, it finds its place in a multitude of industries including electronics, automotive, and communications.
