Heat Shrinkable Tube

A heat-shrinkable tube is used for insulating wires to provide abrasion resistance and environmental protection for wire conductors in the electric field. Furthermore, industries can use it to restore insulated wires by repairing or binding them together to prevent small cables from abrasion.

Heat shrink sleeve also provides entry seals for cables, thus offering outside sealing protection. Additionally, their manufacturing material provides shrinking properties to the tubes essential during the healing process. Shrinking lines for wires design and manufacture are in different varieties and specific chemical makeups with a particular composition dependent on the application for use.

Moreover, each heat shrink sleeve has a specific design and chemical composition that makes it perfect for fulfilling any outward environmental demands. Shrinking lines for cables rating depends on their ability to expand and recovery rate afterward.

What makes up the Heat shrinkable tubes?

Varying application of the heat shrink sleeve requires specific applications. However, manufacturers can use various materials in making these heat shrink sleeves and tubing tubes. These materials include

  • PVC Heat shrink sleeve

PVC Heat shrink sleeve

PVC heat shrink sleeve is available in almost all colors, transparent and opaque variety, and is a lower-cost material. They are primarily applicable outdoors and mostly use an ultraviolet stabilizer for efficient application. PVC heat shrink sleeves tend to burn or char when touched with a soldering iron.

PVC Heat shrink sleeves are effortless and suitable for cable bundling wire joints and repairs. It is mainly used in the home model, making its application ideal and a very economical way of professionally safe electrical connections.

  • Polyolefin heat shrink sleeve

Polyolefin heat shrink tubes are the most commonly used heat shrink stubs and operate at a maximum temperature of between 55 degrees Celsius to 135 Degrees Celsius. Mainly applicable to the railway industries, aerospace, and the military. Furthermore, their flexibility and fast shrinkage ability make them unique.

Polyolefin heat shrink tubing manufacturing comes in varying colors that users can use for color-coding wires. Such dyes include black and transparent colors. However, they have a low resistance to ultraviolet light, and in many cases, industries recommend the black color shrinking tube for cables for outdoor applications. Polyolefin heat shrink tubing can withstand a soldering iron touch.

  • High-Temperature Heat Shrinkable Tube

High-Temperature Heat Shrinkable Tube

Heat Shrink tubing offers resistance to extremely high and shallow temperatures. It’s manufactured from Flouromodified elastomer and applies mainly in situations that require tough resistance to extreme temperatures.

Additionally, its stiff resistance to solvents and other chemical products such as diesel and petrol is a perfect substitute for silicone tubing and has a shrinkage ratio of 2:1.

It’s perfectly suitable for protecting cables and other electrical components due to its high abrasion resistance, even in harsh outdoor conditions. Also, high-temperature heat shrink tubing operates at an optimum temperature of between -75 degrees Celsius and 200 degrees Celsius.

  • Shrink tubes for wires

Shrink tubes for wires are mostly made from Polyolefin and have the advantage of good electrical insulation. This shrinking tube for cable has a polyolefin heat shrinkage ratio of 3:1 and an optimum operating temperature of -100 degrees Celsius and +100 degrees Celsius.

The shrink tube for wires is 212 degrees Fahrenheit and an optimum maximum temperature of 230 degrees Celsius. They are flame retardants for wire bundling, mechanical protection cable joints, and daily repairs.

Shrinking tubes for cables have an excellent rigidity with glue lining as they provide the advantage of suitable tightness, resistance to corrosion, and high temperature. They also have a Heat activated adhesive liner that provides a sealing entry to salt water and other liquids, thus increasing its performance.

Shrinking tubes for cable are fast and easy to use and have an acceptable heat shrink ratio.

  • Heat Shrink Sleeving and tubing

Heat shrink sleeving and tubing cables are a perfect fit to protect tensioned shaft products due to their high mechanical strength and low coefficient of friction. They are ideal for many uses with a shrinkage temperature of approximately 80 degrees Celsius and an approximate 48% shrinkage rate.

Furthermore, they come in varying colors and consist of an approximate diameter of 30 millimeters and a diameter of 18 millimeters. Operates at an ambient temperature of between -40 degrees Celsius to 300 degrees Celsius

A heat shrink cable sleeve applies to electrical insulation and wire cable protection. However, users can use it to prevent corrosion in hydraulic tubes and joints. Also, Home appliances, electrical appliances, and thermal components can use heat shrink sleeving and tubing cables.


Heat shrinkable tubes are ideal for use and application across many home appliances and electrical equipment. Since their manufacturer has varying designs and compositions, it’s easy to pick a choice that fits a user’s preference. Additionally, the quality and efficient performance of the tube is dependable in most applications. Users should look out for the required specifications for their appliances before installation. For more detailed information reach out to approved manufactures.
