　　Military heat shrinkable tube manufacturer : what material is the heat shrinkable tube made of, and what are its characteristics?

　　According to the different usage scenarios and fields, there are many kinds of raw materials for the production of heat shrinkable tubes. The common heat shrinkable tube materials on the market mainly include PVC polyvinyl chloride, PE polyethylene, PVDF polyvinyl fluoride, rubber, PTFE polytetrafluoroethylene, Among them, the performance characteristics and advantages of various materials are different, and the industries used are also different. Let the editor of the manufacturer of military heat shrinkable tubes tell you about it!

　　1. The heat-shrinkable tube made of PVC polyvinyl chloride is called PVC heat-shrinkable tube. Because the raw material is relatively cheap, it has an ultra-thin wall thickness of 0.08-0.15mm, and has a very obvious price advantage. The price is relatively cheap. It is often used in automotive power battery batteries The insulation and protective coating of the core, the rated working temperature of the PVC heat shrinkable tube is usually 85. It will start to soften when it reaches 85.

　　2. PE polyethylene has excellent plasticity and stable physical and chemical properties, so there are many heat-shrinkable products derived from PE polyethylene, from conventional single-wall heat-shrinkable tubes, double-wall heat-shrinkable tubes, high-voltage busbar heat-shrinkable tubes to Thick-walled heat-shrinkable tubes are based on PE polyethylene, so PE polyethylene is also one of the most popular materials in the heat-shrinkable tube industry. The rated working temperature of PE heat-shrinkable tubes is 125. It can meet most ambient temperatures Requirements, the shrinkage ratio is also very wide, from 2 times to 6 times, there are more than ten standard colors to choose from.

　　3. PVDF polyvinyl fluoride is also called fluorine plastic, PVDF heat-shrinkable tube is resistant to aging, corrosion, high temperature, biological inertness, and chemical corrosion resistance, so it can be used to coat medical equipment pipelines and protective sleeves that require high-temperature precision components, PVDF Heat-shrinkable tubes are used in motorcycle brake lines. According to the hardness, they are divided into two types: 150 and 175. The surface has high gloss and high flame retardancy.

　　4. Rubber heat-shrinkable tubes are divided into silicone rubber heat-shrinkable tubes and fluororubber heat-shrinkable tubes, both of which can meet the requirements of the rated working temperature of 200°C. Soft, it is one of the very good heat shrinkable tubes at present, usually used in food and medical fields, and can reach food grade standards, fluorine heat shrinkable tubes are widely used in environments that require high temperature resistance to oil and chemical solutions to protect their cable ducts Protected from corrosion by high temperature liquids.

　　5. PTFE Teflon heat-shrinkable tube is currently the heat-shrinkable tube industry with very good high-temperature resistance, and its rated working temperature can reach 260. It has the characteristics of low adsorption, high sliding, high flame retardancy, and corrosion resistance. It can resist For most strong acids and bases, the standard color of Teflon heat shrink tubing is generally translucent with a whitish tinge.

　　Based on the above five points, the advantages of PVC-PVC and PE-PE heat-shrinkable tubes are low price and wide application. The heat-shrinkable tubes produced by polyvinylidene fluoride, fluorine rubber, and polytetrafluoroethylene can meet the requirements of solution resistance and high temperature resistance. , according to the above characteristics of heat shrinkable tubes of different materials and the application environment of your own products, you can choose a suitable heat shrinkable tube.

　　The above is the content explained by the editor of the military heat shrinkable tube manufacturer . I believe everyone has a certain understanding. If you need to know more, please contact our military heat shrinkable tube manufacturer. Professionals will serve you.
