Heat Shrink Tube Kit

Heat shrink tubing kits are a set of flexible, shrinkable tubes made of materials such as polyolefins (polyethylene, PVC) that shrink when exposed to heat. These kits are widely used for insulation, protection, and environmental sealing of wires, cables, and other components across a wide range of industries. The heat shrink tubing in the kits is available in a variety of sizes and lengths, allowing users to select the appropriate heat shrink tubing for different applications.

When heated, the tubes shrink radially and fit tightly to the object, protecting it from environmental factors such as moisture, dust, chemicals, and mechanical damage. In addition to electrical insulation, heat shrink tubing is also used in applications that require stress relief, vibration reduction, and protective coating of components.

Main Features of FANGBE Heat Shrink Tubing Kits:

Material: Polyolefin

FANGBE's heat shrink tubing is made of polyolefin (a polymer) and has excellent properties in terms of flexibility, insulation, and heat resistance. Polyolefin is lightweight, chemically resistant, and suitable for a wide range of temperatures and applications.

Low Shrink Temperature: Polyolefin heat shrink tubing only requires a low shrinking temperature, usually starting to shrink around +70°C. This makes them ideal for heat-sensitive applications.

Full Shrink Temperature: When exposed to temperatures around +125°C, they fully shrink, ensuring a tight protective cover for components.

Flame Retardant Properties:

The material has flame retardant properties to meet stringent safety requirements. It effectively prevents fire hazards, making it suitable for environments where flame retardancy is critical.

Safe and Non-Toxic: Heat shrink tubing is safe for both industrial and consumer use and contains no harmful chemicals or toxins, which makes it ideal for electronics and devices that may come into contact with users.

Flexible and Elastic: Even after shrinking, the tubes remain elastic and soft, ensuring they fully conform to the shape of the underlying components.

Good Insulation Properties: In addition to mechanical protection, heat shrink tubing provides excellent electrical insulation, helping to maintain safety standards for electrical installations.

Technical Specifications of Heat Shrink Tubing:

Material Type:

Polyvinyl Chloride (PVC): The heat shrink tubing in the FANGBE kit is made of PVC, a versatile and durable plastic with excellent flexibility and resistance to physical stress.

Shrink Ratio:

2:1 Shrink Ratio: This means that the heat shrink tubing shrinks to half of its original diameter when heated. This ratio is ideal for general purpose use, providing a good balance between flexibility and tightness for a wide range of cable and wire sizes.

Temperature Requirements:

Start Shrink Temperature: +70°C (relatively low temperature, convenient for use with standard heat sources).

Full Shrink Temperature: +125°C (ensuring a tight, secure fit to protect components).

Minimum Shrink Temperature: ≥ 84°C (provides an additional safety margin).

Operating Temperature: The material remains stable and flexible over a temperature range of -55°C to +125°C, providing versatility for both high and low temperature applications.

Mechanical and Electrical Properties:

Tensile Strength: 10.4 MPa (measures the force per unit area required to break a material. This ensures that the material can withstand significant stress without tearing).

Dielectric Strength: 15 kV/mm (excellent resistance to electrical breakdown, ensuring reliable insulation in electrical applications).

Shrinkage and Performance Characteristics:

Axial Shrinkage: When heated, heat shrink tubing shrinks approximately ±5% in the axial direction (lengthwise). This feature is particularly useful for tightly covering connectors or irregularly shaped components.

Fast Shrink Time: The heat shrink tubing in the kit is designed to shrink quickly, shrinking in just seconds when exposed to a heat source. This fast response time makes installation faster and more efficient.

High-Quality Construction: The materials are carefully crafted to ensure that the tube provides excellent protection and has an aesthetic appearance even after shrinking.

Applications and Use Scenarios:

Heat shrink tubing kits are used in a variety of industries, each of which requires specific qualities from the materials. Here are some common applications:

1. Electrical and Electronic Industries:

Wire and Cable Insulation: Heat shrink tubing is often used to insulate wires and cables, ensuring safe and reliable operation and preventing short circuits or damage from physical wear and tear.

Wire Bundling: Heat shrink tubing helps bundle multiple wires or cables together, reducing clutter and improving the overall organization of wiring systems in electronic equipment, vehicles, and machinery.

Cable Repair: Heat shrink tubing can be used to repair damaged sections of cables, providing a quick and effective solution without the need for complex rewiring.

2. Automotive Industry:

Wire and Cable Insulation: In automotive wiring systems, heat shrink tubing is used to protect wiring from mechanical stress, heat, and chemicals such as oils, coolants, and salt.

Connector Protection: Electrical connectors in vehicles are often coated with heat shrink tubing to protect them from moisture, dirt, and corrosion.

3. Telecommunications:

Cable Protection: Heat shrink tubing is essential for protecting telecommunications cables, especially in outdoor installations where they need to withstand UV rays, moisture, and physical wear and tear.

4. Industrial Applications:

Machine Wiring: In manufacturing and industrial equipment, heat shrink tubing is used to insulate control systems and machinery wiring, ensuring safe operation in harsh environments.

Environmental Sealing: Heat shrink tubing is used to seal sensitive components from dust, dirt, and water, making it ideal for industrial sensors and motors.

5. Medical Devices:

Insulating Medical Cables: Heat shrink tubing provides insulation and protection for medical device wiring, which needs to meet safety standards for patient use.

Sealing Medical Components: In applications such as blood pressure cuffs or diagnostic equipment, heat shrink tubing helps protect and seal electrical components from environmental hazards.
