Materials can be divided into PE heat shrinkable sleeving, PTFE heat shrinkable sleeving, silicone heat shrinkable sleeving, pvc heat shrinkable sleeving, PET heat shrinkable sleeving, irradiated cross-linked PE heat shrinkable sleeving, 10KV high voltage busbar protection heat shrinkable sleeving, 35KV high voltage busbar protection heat shrinkable sleeving, double wall heat shrinkable sleeving with adhesive, heat shrinkable sleeving.

The material of the heat shrink tube is selected according to the type of heat shrink tube use, there is no material good or bad.

For battery capacitors, the requirements are ultra-thin, fast shrinkage and a lot of colours, mostly in PVC and PET heat shrinkable tubes.

For general electronics, such as wire connectors, which require softness and resistance to low voltage 600V, EVA material is used.

For electricity, where there is a requirement for softness and resistance to high pressure, EVA with rubber.

For those requiring abrasion resistance, PE or HDPE material can be used.

If high temperature resistance is required, fluoroelastomer, polyvinylidene fluoride, Teflon material, etc. can be used.

There are other special requirements, such as resistance to low temperatures, oil and special corrosive liquids, and different material options are available.

At present, the heat shrink industry is more powerful, and responsible enterprises, such as the long garden, Hong Shang, will provide different products according to different customer needs. Some small enterprises, that is really "one for a hundred", no matter what your needs, are only to recommend you what he has, but not what you need.

Heat shrinkable tube is divided into low-voltage and high-voltage, low-voltage is generally a thin tube, used in the harness cable joints more, there is also a whole cable are wrapped, this is less, there is a high-voltage heat shrinkable tube, used in 10kv/20kv and 35kv and above the insulation protection of live equipment, there are some are used in specific products, such as used in copper row on the copper row heat shrinkable tube or bus bar heat shrinkable tube, used in fish rods on the pattern tube, etc., there are some special heat shrinkable tube, such as high temperature resistance, corrosion resistance, UV resistance, pressure resistance, fire retardant, etc.
