The temperature range of heat shrink tubing varies due to its material and application scenarios. The following is a summary of the temperature range classified according to different materials and uses:
1. Conventional heat shrink tubing
Temperature range: -55℃ to 125℃
Conventional heat shrink tubing is mainly made of polyethylene, polyvinyl chloride and other materials, suitable for wire and cable protection and electronic component protection in general environments.
2. High temperature heat shrink tubing
Temperature range: -80℃ to 280℃
High temperature heat shrink tubing is made of special materials such as polytetrafluoroethylene (PTFE), fluororubber, etc., suitable for higher temperature environments. For example, PTFE heat shrink tubing can work in the range of -200℃ to 200℃, and will not be damaged even if exposed to 400℃ for a short time.
3. Special purpose heat shrink tubing
Medical grade PTFE heat shrink tubing: The temperature range can reach -200℃ to 260℃, and the short-term temperature limit is above 500℃, which is suitable for high temperature protection of medical devices.
Oil-resistant elastomer heat shrink tubing: The temperature range is -75℃ to 150℃, suitable for high-temperature fluid environments such as military vehicles and high-speed trains.
4. Other high-temperature heat shrink tubings
175℃ semi-rigid polyvinylidene fluoride heat shrink tubing: The temperature range is -55℃ to 175℃, suitable for occasions requiring high temperature and wear resistance.
150℃ polyolefin heat shrink tubing: The temperature range is -55℃ to 150℃, with softness and high temperature flame retardant properties.
Summary
The temperature range of heat shrink tubing ranges from -55℃ to 500℃, and the specific selection needs to be determined according to the actual application scenario and material properties. For example, 125℃ heat shrink tubing can be selected for conventional environments, while high-temperature heat shrink tubing such as PTFE or fluororubber needs to be selected for high temperature or special environments.
