Dual wall Teflon (polytetrafluoroethylene) heat-shrinkable tube

It is also called high temperature Teflon heat-shrinkable tube with glue, double-layer PTFE heat-shrinkable tube, transparent color sensor protection Teflon heat-shrinkable tube. At present, due to the characteristics of Teflon, there is no real double-walled Teflon heat-shrinkable tube like the double-walled glued heat-shrinkable tube. Certain products require Teflon heat-shrinkable tubes to be completely sealed, waterproof and gas-proof. Hence the double layer Teflon.

A sensor is a detection device that can sense the measured information, and can transform the sensed information into electrical signals or other required forms of information output according to certain rules, so as to meet the requirements of information transmission, processing, storage, and display. , recording and control requirements.

The thermocouple or thermal resistance in the sensor probe is small and sensitive. Sealing protection is required, especially for temperature sensor probes that require a certain degree of high-temperature resistance, and some probes that require more chemical resistance. The thermal resistance or thermocouple in the armored tube needs to be protected by Teflon heat shrinkable tube.

On the basis of single-layer Teflon heat shrinkable tube, a double-layer Teflon heat-shrinkable tube can provide stronger protection for components. After shrinking, the double-layer Teflon is completely fitted and sealed, which can effectively prevent the damage of water and gas to the working components.

After shrinking, the double-layer Teflon heat-shrinkable tube is completely fitted and sealed, which eliminates the interference of external factors on the detection results and improves the detection accuracy. It is also because of the complete fit and sealing protection, which prolongs the service life of the sensor. The quality of the sensor is a huge improvement.
