Difference Of Dual Wall And Medium Wall Heat Shrink Tubing

We commonly used with two kinds of heat shrinkable tube:dual-wall heat shrinkable tube and medium wall heat shrink tubes, then let's talk about the difference of dual wall shrink tubes and medium wall shrink tubes .

Dual-wall heat shrinkable tube and medium wall heat shrink tube in general is about the same, with the following four different:

First, the diameter of the pipe is different: the diameter of the wall heat shrinkable tube dual-wall heat shrinkable tube, softness is relatively small; dual-wall heat-shrinkable tube is a small gauge, sealing performance is very good.

Second, the coating process is different, dual-wall heat shrinkable tube is simultaneously extruded, uniform thickness thin layer, the naked eye can be seen clearly two layers, medium wall heat shrinkable tube coating methods are divided into straight and spiral coating, straight coating The glue shows straight stripes on the inner wall, while the spiral glue shows the inner wall presents an arc ring.

Third, the high temperature is not the same, the medium wall heat pipe continuous use temperature: -55 ℃ ~ 105 ℃, the minimum initial shrinkage temperature: 80 ℃, the minimum complete shrinkage temperature: 120 ℃, the basic and double- Only the maximum temperature on the double-wall heat-shrinkable tube can reach 125 ℃, and medium wall heat-shrinkable tube up to 105 ℃ heat shrink tube on the continuous work, in fact, the maximum temperature on the continuous work, the life of the material will be greatly Shortened, they are also better at low temperature brittleness, at: -55 ℃ above the temperature of continuous work without brittleness.

Fourth, the application is different: double-wall heat-shrinkable tube for wiring waterproof electronic equipment, leak-proof, water pumps and submersible pumps waterproof, underwater lighting, automotive tubing, advanced line beam and other occasions. Medium Wall heat shrinkable tube for small diameter steel, stainless steel and other hard objects outside the anti-corrosion, reinforcement, such as acoustic pipe, concrete buried pipe connection waterproof, anti-corrosion.
