Heat shrink tube

Definition and principle

Heat shrink tubes are usually made of high polymer and have a "memory effect". In the production process, through radiation crosslinking or chemical crosslinking and other processes, so that it can obtain a special molecular structure. When heated to a certain temperature, the molecular chain segment begins to move, and the material will shrink back to the initial state before crosslinking, tightly wrapping the protected object, which is the basic principle of heat shrink tube work.

Material classification

Common heat shrink pipe materials are polyolefin, fluorine plastic and so on. Polyolefin heat shrink pipe is widely used, and has the advantages of moderate price, good insulation performance and good flexibility. Fluorine plastic heat shrink pipe is more prominent high temperature resistance, corrosion resistance, often used in special occasions with high environmental adaptability requirements, but the cost is relatively high.

peculiarity

Excellent insulation performance: can effectively isolate the current, prevent leakage, ensure the safe operation of electrical equipment, often used in wire and cable insulation protection.

Various shrinkage ratios: there are different shrinkage ratios to choose from, which can adapt to the needs of various sizes of objects, and has strong versatility.

Chemical corrosion resistance: It has good tolerance to many chemical substances and can protect objects from erosion in harsh chemical environments.

Good mechanical properties: with a certain strength and toughness, can resist a certain degree of friction, stretching and extrusion, to protect the internal objects from external damage.

Application field

Electronic appliances: In the manufacture of electronic equipment, used for wire and cable connection parts insulation protection, solder joint protection, as well as circuit board components fixed and identification. For example, the internal wire connection of the computer, the line protection of the mobile phone charger, etc.

Power industry: as an insulating and protective material for cable terminals and intermediate joints, to improve the safety and reliability of cable operation; It is also used for insulation protection of busbar trough to prevent short circuit between phases.

Automotive industry: Used for wrapping and protection of automotive wire harnesses, which can resist harsh environments such as high temperature, oil pollution and humidity, and extend the service life of wire harnesses; It can also be used for the identification of auto parts.

Communication field: Protect optical fibers, network cables and other communication cables, enhance their anti-interference ability and mechanical properties, and ensure stable signal transmission.
