Adhesive heat shrink tubing
3:1, dual wall heat shrink tubing is a cross-linked polyolefin tube that is extruded with an inner layer of adhesive. Upon recovery of dual wall heat shrink, the inner layer of adhesive will melt and flow.
Features
1. 3:1 shrink ratio
2. Longitudinal shrink ratio: ≤+8%
3. Out jacket flame retardant, inner adhesive self-extinguished
4. Super sealing against water, moisture or other contaminants
5. Continuous operating temperature: -55℃~ 125℃
6. Shrink temperature: 120℃

FAQs
What’s the meaning of shrink ratio?
Dual wall heat shrinkable tube will shrink when you heating the tube, sometimes also called thermal shrinkage rate, shrinkage ratio, it refers dual wall heat shrinkable tube before and after shrinking ratio of inner diameter, for example, as supply ID 6 mm, the after shrinking diameter is 3 mm, then we say shrinkage is 2:1, as we know 6/3mm=2:1 ratio, if the ID 6mm tube after shrinking ID is 2mm max, it’s 6/2=3:1 shrink ratio.
Is installation of the heat shrinkable tubing difficult?
No, in most instances, heat shrink tubing is very easy to work with and simple to install.
Heat shrink tubing is available in an array of sizes and colors, step1 find the correct size of tube to the wire, Step 2, cover the wire by heat shrink tube, then heat the heat the tube with hot gun at it’s full shrinking temperature, the tube will shrink on to the wire.
