Model: CB-DWT (4x)

Material
Exterior layer: cross-linked modified polyolefin resin
Inner layer: hot-melt adhesive

Shrink ratio: 4:1

Applications
The dual wall 4:1 heat shrink tubing is an adhesive-lined, flexible, flame-retardant and environmentally friendly tubing that features an excellent water resistance and moisture resistance. This heat shrink tubing is widely used as waterproof shrink tubing for wire linkage of electronic devices, as corrosion prevention tubing for metal tubing and as seal tubing for cable branches. The dual wall 4:1 heat shrink tubing can also be used against looseness caused by polymer chain relaxation.
