What is the shrink ratio of the adhesive lined heat shrink tube? How many different shrink ratios of adhesive lined heat shrink tube? Which is the common shrink ratio? We will explain these one by one.

First, we have to understand is what adhesive lined heat shrink tube shrink ratio is?

Heat shrink tube will shrink after heating, so only things can shrink have this shrink ratio parameter. It refers to the adhesive lined heat shrink tube at room temperature, for example inner diameter is Φ6mm, after shrinking, for example it becomes Φ3mm, then we say shrink ratio is at the ratio of before shrink inner diameter to after shrink inner diameter, ie 6/3 = 2/1, the 2: 1 is the shrink ratio. Shrink ratio reflects pipe contractility. The higher the shrink ratio, the better and thinner after the heat shrink tube fully contracted. If the adhesive lined heat shrink tube before shrinkage is Φ6mm, after shrink is Φ2mm, only two millimeters left in size. Its shrink ratio is 6: 2, which is 3: 1, if that is 1.5mm after shrinking, so shrink ratio is 4: 1. When it comes to shrink ratio, then we will continue to talk about the wall thickness, as it stretched wall thickness will become thin to thick wall thickness after the shrinking. For adhesive lined heat shrink tube, the more important after shrink wall thickness, because after shrink wall thickness is in the state of protection. We are talking about adhesive lined pipe radial shrinkage refers to the shrinkage. Because theoretically, it is not allowed to change the longitudinal of the tube.

Volsun adhesive lined heat shrink tube by shrink ratio can be divided into the following kinds: 2: 1, 3: 1, 4: 1 environmental adhesive lined heat shrink tube; 3: 1 low temperature thick adhesive lined heat shrink tueb; 3: 1 heavy wall adhesive line heat shrink tube; 3: 1, 4: 1 military grade adhesive lined heat shrink tube; 4: 1 VBK adhesive lined heat shrink tube; 6: 1 high shrink ratio adhesive lined heat shrink tube etc.
