How To Choose A Correct Heat Shrink Tubing
Heat shrink tubing was widly used in many fields now, include Component protection , Electric power industry ,communications industry , auto industry and so on. Heat shrink tubing was easy to be installed ,and has certain functions : waterproof, oil resistance , anti-corrosion , resistant to high voltage , high temperature resistance and so on. So when you need heat shrink tubing, you must confirm your requirement first. For examples

1. You need heat shrink tubing to repair cables, just repair the fracture surface no other requirement , you can choose Single wall heat shrink tubing(HHST), some one also call it heat shrink tubing without glue , normally it is made of PE or PVC , PE is environmentaly , PVC is chipper.

2. You also wish the heat shrink tubing waterproof, for example you want to repair cable outside , it will contact with water, you should choose Dual wall heat shink tubing(DHST) , also called heat shrink tubing with glue. There are difference between single wall heat shrink tubing and dual wall heat shrink tubing, first dual wall heat shrink has a layer of glue inside , it is specially designed for sealing and waterproofing , single wall heat shrink tubing has not ; second , the wall thickness of dual wall shrink tubing is thicker than single wall heat shrink tubing.

3.If you want to use it in a high temperature environment, you must tell the seller the maximum service temperature.

4.If there is high flexibility requirements, you can choose silicone heat shrink tubing(HSST) , pay attention: silicone heat shrink tubing easy to adsorbing dust.

5.If you want use it in car, you can choose Diesel resistant heat shrink tubing (DRHST).

6.If you need it resistant to high voltage, choose bus bar heat shrink tubing (HBBT) In short when you perchase heat shrink tubing, you should tell the seller your requirement , inclue : service environment , inner diameter , color , shrink ratio , they will recomend you a right type !

Convert the flat width of heat shrink tube into inner diameter
Do you come across the situation ? You want to by some heat shrink tube, the seller ask you that which size do you need ? Ordinary, the size is inner diameter , but you just kown the flat width of the heat shrink tube , because it was flat when you received it. You can convert the flat width into inner diameter yourself, it is very easy : ineer diameter x 3.14 / 2 = Flat width.

For example : the flat with is 18mm, 18x2/3.14=11.5mm, and you should add the wall thickness of heat shrink tube about 0.5mm , so you can tell him , you need 12mm inner diameter heat shrink tube.

Heat shrink cable repair tubing
It’s been a long time that we repaire cable by electrical tape before, although it is insulation but not waterproof , and easy to come off. So many people use heat shrink tubing instead electrical tape now.

We will come across 2 situations

1. The cable can be cut off then Reconnect. We can choose ordinary heat shrink tubing.

2. The cable can not be cut off. You can choose Heat shrink cable repair sleeve. It is easy to install.

Features

Quick and easy installation >Covered with thermo paint >Protection against mechanical stress >Sleeve and channel can be cut to suit shorter applications >For insulation on low voltage cable up to 1000V >Hot melt adhesive forms a durable, moisture resistant seal >Fit a wide range of cable sizes
