FAQ:

1) Inner diameter of dual wall heat shrinkable tube

We know that the cross section of the casing is cylindrical, the distance between the inner wall is the tube inner diameter, we usually use Φ to state tube inner diameter, because it used to label the diameter in engineering, and then followed by a digital value, such as Φ6mm, means the tube inner diameter is 6mm when the tube is round.

 

2) Shrink rate of dual wall heat shrinkable tube

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.

 

The shrinkage rate reflects the shrinkage capacity of the double wall heat shrinkable tube, the higher the shrinkage rate, the small the diameter after contraction. If the before shrinking inner diameter is 6 mm, and after shrinking diameter is 2 mm, then its shrinkage is 6:2, that is, 3:1. If before shrinking ID is 6 mm, after shrinking ID is 1.5mm, then the contraction rate is 4:1, usually, dual wall heat shrinkable tube shrink rate including 2:1, 3:1, 4:1,etc.

 

3) Adhesive in the dual wall heat shrinkable tube.

Why this heat shrink tube be called double wall heat shrinkable tube? because the inner part of the heat shrinkable tube is coated with a layer of glue, which is a hot melt adhesive, the glue is solid at room temperature and will melt into liquid glue when it is hot, he hot melt adhesive of dual wall heat shrinkable tube is mostly white and transparent.
