[Summary]Although heat shrink tube has better various protective properties, but under different environments, its aging degree will be greatly different. The application period of heat shrink tube under all normal natural environments is 15 years. In chemical plants, crude oil in coastal areas and other regions, environmental pollution, corrosive vapors, corrosion resistance, etc. are more serious, which will seriously damage the service life of heat shrink tube. The general service life is about 5 years.

The performance of the heat shrinkable tube is believed to be well understood by everyone. Although heat shrink tube has a long service life, incorrect application can easily aggravate the aging rate of the tube, thereby shortening the service life of heat shrink tube. Let's talk about the aspects of aging problem of heat shrink tube.
1.Use environment
Although heat shrink tube has better various protective properties, but under different environments, its aging degree will be greatly different. The application period of heat shrink tube under all normal natural environments is 15 years. In chemical plants, crude oil in coastal areas and other regions, environmental pollution, corrosive vapors, corrosion resistance, etc. are more serious, which will seriously damage the service life of heat shrink tube. The general service life is about 5 years.
2. Operating temperature
Heat shrink tube has superior high-temperature resistance. Heat shrink tube of different materials have different high temperature resistance. Long-term operating temperature of conventional heat shrink tube is about -55 to 125 degrees. In addition, it is necessary to pay attention to temperature control during the heating and shrinking process. The firepower point is not well grasped, which may easily cause the surface layer of heat shrink tube to burn or blacken, which not only reduces the characteristics of the insulating layer but also reduces the service life.
3. Quality problem of heat shrink tube
Some manufacturers will use fake and inferior raw materials to fill them in order to control costs, resulting in the commodities unable to meet the technical standards. This type of heat shrink tube cannot meet the general wall thickness requirements, and its protection performance has been reduced , It will be easier to aging during use.
