How to choose the type of fuel tube  

一、Determining the contraction speed of heat shrink tubes

Shrinkage rate as an important performance parameter of heat shrink tube is an important indicator that cannot be ignored when selecting heat shrink tube. At present, the commonly used shrinkage rate of heat shrink pipes is 2, 3 and 4 times, and the maximum shrinkage rate is 6 times. Typically, given the same specifications, the larger the reduction, the higher the price. 2x, 3x, 4x can be used to produce single wall heat shrink tubes as well as double wall bonded heat shrink tubes, while 6x heat shrink tubes due to the high shrinkage rate can only produce medium wall bonded heat shrink tubes.

二、Determination of operating temperature

The operating temperature of heat shrink tubing varies depending on the type and material, with a maximum temperature tolerance of 105°C to 260°C. In some special cases there are also minimum operating temperature requirements ranging from - 65°C to - 45°C. Therefore, it is necessary to have a general understanding of the operating temperature of heat shrink tubing. According to the maximum level of heat resistance, they can be divided into seven levels: 105°C, 125°C, 135°C, 150°C, 175°C, 200°C and up to 260°C. You can choose the appropriate heat shrink tube according to your product requirements.

三、 Definition of usage scenarios and purposes

Heat shrink pipes according to their application can be divided into food and medical heat shrink pipes (silicone heat shrink pipes and PVDF heat shrink pipes), sealed waterproof heat shrink pipes. You can select the appropriate heat shrink tube according to the application conditions and product specifications.

四、 Definition of inner diameter specifications

Selecting the inner diameter specification is relatively simple, simply measure the maximum and minimum size of the product to be wrapped. If the connection between the connector and the cable needs to be protected, simply use a ruler to measure the diameter of the wire and the outer diameter of the connector, and then select the corresponding diameter of the heat shrink tube according to the outer diameter of the connector. Do not size heat shrink tubing based on wire diameter as this may interfere with connector installation. The inner diameter of the heat shrink tube should be selected according to the larger end.

五、Color selection

Hot pipes have a fuller color. Black is the color of all heat shrink tubing materials. PE polyethylene heat shrink tubing has 11 standard colors, including black, white, clear, grey, brown and red, orange, yellow, green, blue and purple. It should be noted that clear PE heat shrink tubing is not fire resistant. Land heat shrink tubes can be made in yellow and green colors, and Ko UACE heat shrink tube manufacturer can customize two-color striped heat shrink tubes.

To select the specification of heat shrink tubing, only five basic parameters are required: contraction speed, operating temperature, use environment, inner diameter and color. Using these five factors, it is easy to select suitable high-quality heat shrink tubing. If you are not sure what type and specification of heat shrink tubing you are using, you can contact online heat shrink tubing manufacturer KEYUACE. A heat shrink tube manufacturer can help you select the right heat shrink tubes, providing one-stop service from selection to delivery.
