Advantages and disadvantages of heat shrinkable tube

Heat shrinkable tubes are used in electronic products to insulate electrical components, seal cables against moisture and other contaminants, provide stress relief, especially at the end of the cable, and prevent cable wear and other mechanical abuse.

Advantages of heat shrinkable tube

1. Heat shrinkable tube has good insulation performance and high temperature resistance, can be used in high temperature environment.

2. High shrinkage rate, good appearance quality, can be made into various shapes of products.

3. The heat shrink tube has high chemical stability and can maintain the original characteristics for a long time.

4. Small surface tension, good self-lubrication performance, easy to clean.

5. The coating is hygienic, after high temperature curing into a film, the coating itself is pollution-free and does not contain heavy metal ions.

6. Heat shrink tube has good mechanical and electrical properties.

Disadvantages of heat shrinkable tube

1. Low production efficiency and limited product length.

2. Not suitable for making large size products.

3. High temperature is required during processing, which may affect the health of operators.

4. The relatively high price is not suitable for mass production.

5. In some specific applications, factors such as temperature resistance and fire resistance of materials may need to be considered.
