What is Teflon heat shrink tubing?

    Teflon heat shrink tubing is a heat shrink sleeve made of Teflon, so it is called Teflon heat shrink tubing. Also known as polytetrafluoroethylene heat shrink tubing (Polytetrafluoroethene), the English abbreviation is PTFE. Teflon is known as the "King of Plastics". It is a synthetic polymer material that uses fluorine to replace all hydrogen atoms in polyethylene. This material is resistant to acids, alkalis, and various organic solvents, and is almost insoluble in all solvents. At the same time, Teflon heat shrink tubing has the characteristics of high temperature resistance and can work at high temperatures of 260°C for a long time without deformation.

    Teflon heat shrinkable tubing uses polytetrafluoroethylene resin as raw material. During the processing and production process, the product is forced to deform with high elasticity. This deformation is reversible and is in a frozen state at low temperatures. If it is exposed to a high temperature of 350°C again, it will Unfreeze this frozen state and gradually return to its original state.

    Teflon heat shrink tubing has extremely strong low-temperature and high-temperature resistance and can work for a long time in the temperature range of -55°C to 260°C. It is not brittle or deformable, achieving safe and reliable protection. The shrinkage ratios are 1.7:1 and 4:1. The color is mainly transparent (milky white). The normal inner diameter is 1.0mm-14mm. Large-sized Teflon heat shrinkable tubes can be customized. The cross-section of the Teflon casing is cylindrical, and the inner diameter is the inner diameter of the pipe wall. The shrinkage temperature of Teflon heat shrink tubing is generally around 350°C.

What is the function of Teflon heat shrink tubing?

    It has the characteristics of high temperature resistance, corrosion resistance, high pressure resistance, flame retardant and long-term non-aging. Widely used in aerospace, instrumentation, textile and chemical industry, food and medical care, electronic appliances, postal and telecommunications, petrochemical industry, metallurgical electronics, railway transportation, motor appliances, household appliances, high-rise buildings, lighting, special transformers, special cables, sensors , thermal components and other industries. Teflon heat shrinkable tubes play an important role in the national economic fields such as chemical industry, machinery, electronics, electrical appliances, military industry, aerospace, environmental protection and bridges.

Exploring the Functionality and Applications of Teflon Heat Shrink Tubing

    Although Teflon heat shrink tube is not an important component in the manufacturing of motors, new energy vehicles, rail transit, aerospace appliances, etc., its protective role is crucial. You must choose the appropriate Teflon heat shrink tube. It is the basic condition to understand its various characteristics and performance before you can choose a suitable high-temperature resistant Teflon heat shrinkable tube.
