Question

What is the shrinkage ratio?

Answer

Shrink ratio is the correlation between the diameter of the tube before shrinkage and after shrinkage. In other words, a tube with shrink ratio 2:1 will be 2 times smaller after shrinkage, a tube with shrink ratio 3:1 will be three-time smaller and so on. The more the shrink ratio is the more complicated is the production process of this tube. The tube with a big shrink ratio is very useful in cases when you work with lots of different diameters.
