Application fields

Electrical and electronic fields

Cable protection: Use heat shrink tubing at the connection between cables and wires to provide insulation and mechanical protection to prevent short circuits and leakage.

Circuit protection: Use heat shrink tubing around circuit boards and connectors to protect components from dust and moisture.

Battery pack packaging: Wrap heat shrink tubing around the outside of the battery pack to protect the battery from physical damage, chemical corrosion, and moisture intrusion.

Automotive industry

Wire harness protection: Heat shrink tubing is widely used to protect automotive wiring harnesses to prevent wear caused by vibration and friction and extend the service life of the wiring harness.

Waterproof sealing: Use heat shrink tubing at the electrical connection of the car to help seal the interface, prevent water vapor intrusion, and ensure the reliability of the circuit.

Marking and sorting: Use heat shrink tubing of different colors to mark and sort the wires in the car for later maintenance.

Communication and network

Fiber optic protection: Heat shrink tubing is used on the fiber optic welding point to effectively protect the fiber optic connector and prevent breakage and moisture.

Cable protection: Use heat shrink tubing at the interface of communication cable and network cable to prevent signal interference and external damage.

Industrial Manufacturing

Pipeline Protection: Heat shrink tubing is used for pipe connections in industrial equipment to prevent corrosion, wear and chemical erosion.

Tool Anti-slip: Wrapping heat shrink tubing on the handle of the tool can increase friction, play an anti-slip role, and improve the user experience.

Marking and Packaging: Heat shrink tubing is used in industrial production to color-code and mark cables and pipes for management.

Aerospace

Cable Protection: Cables and connection points in aerospace equipment need to operate under extreme conditions. Heat shrink tubing provides insulation, waterproofing and anti-vibration protection to ensure connection stability.

High Temperature Protection: Heat shrink tubing made of special materials can withstand high temperatures and is suitable for the special temperature requirements of aircraft and spacecraft.

Medical Equipment

Device Coating: Wrap heat shrink tubing on some medical equipment and surgical instruments to provide insulation protection and prevent contamination.

Cable and Pipeline Protection: Used to protect cables of medical equipment to prevent wear caused by frequent operation or cleaning.

Home Appliances

Internal Wiring of Small Appliances: Heat shrink tubing is used to wrap wires inside home appliances to avoid short circuits and leakage and enhance safety.

Waterproof protection: Heat shrink tubing is used in water-related parts of household appliances, such as washing machines, water pumps, etc., to prevent cables from being damaged by water.

FAQ

Q: Why does the heat shrink tubing break during the shrinking process?

A: The rupture of the heat shrink tubing is usually caused by uneven heating or too high temperature. When using a heat gun, the appropriate temperature should be maintained and the heat should be evenly heated around the heat shrink tubing to avoid overheating and brittle material. In addition, when selecting the heat shrink tubing, make sure that it is of the right size. Too small a diameter is prone to uneven force and breakage during shrinkage.

Q: What is the general shrinking temperature of the heat shrink tubing?

A: The shrinking temperature of most polyolefin heat shrink tubing is between 90°C and 120°C, and the shrinking temperature of heat shrink tubing of different materials may be different. Before use, refer to the product manual to ensure the correct heating temperature to avoid affecting the heat shrinking effect due to insufficient or excessive temperature.

Q: How to choose the right size of heat shrink tubing?

A: When selecting a heat shrink tubing, the diameter should be selected according to the diameter of the object being covered. The inner diameter of the heat shrink tubing usually selected should be 20%-30% larger than the diameter of the object being covered. For example, if the diameter of the protected cable is 5mm, select a heat shrink tubing with a diameter of 6-7mm so that it can be tightly wrapped after shrinking.

Q: Is heat shrink tubing waterproof?

A: Some heat shrink tubing with inner glue (double wall) has good waterproof performance. After shrinking, the glue layer will fit tightly with the covered object to form a sealing effect, which is suitable for occasions that need waterproofing. Single-wall heat shrink tubing is usually not completely waterproof, but it can provide certain moisture protection.

Q: Can heat shrink tubing be reused?

A: Heat shrink tubing is generally not reusable. After heating and shrinking, it will permanently adhere to the surface of the covered object and cannot be restored to its original shape. If it needs to be replaced or re-wrapped, you can only cut the original heat shrink tubing and use a new one.

Q: What are the heating methods when using heat shrink tubing?

A: Common heating methods include using a heat gun, oven or lighter. The heat gun is the most common and even heating method. The oven is suitable for large-scale processing, and the lighter is suitable for small-scale use, but be careful to avoid local overheating.

Q: Will the heat shrink tubing affect the wires after use?

A: High-quality heat shrink tubing will not have a negative impact on the wires, but will provide additional protection. However, it is important to use a moderate temperature to avoid overheating and damage to the insulation layer of the wire. In addition, heat shrink tubing made of different materials may have different physical effects on wires. Improper selection may cause the wire to become hard or unevenly stressed.

Q: What is the temperature resistance of heat shrink tubing?

A: Heat shrink tubing made of different materials has different temperature resistance. Generally, heat shrink tubing made of polyolefin materials has a temperature resistance range of -55°C to 125°C, while special materials (such as fluoroplastics) can reach a temperature resistance of more than 200°C. When selecting, the appropriate material should be selected according to the temperature requirements of the specific application environment.

Q: Does the heat shrink tubing have UV protection?

A: Some heat shrink tubing has UV protection and is suitable for outdoor applications. It can prevent aging or brittle cracking caused by long-term exposure to sunlight. If used outdoors, it is recommended to choose heat shrink tubing marked with UV protection.

Q: How to judge whether the heat shrink tubing is completely shrunk?

A: After the heat shrink tubing is completely shrunk, it will fit tightly to the surface of the covered object, and there will be no obvious wrinkles or looseness on the surface. You can check by touch whether the surface fits the cable or connection point tightly. If not, further heating is required.
