Heat Shrink Tubing and Heat Shrink Moulded Shapes for your Applications

The perfect Cable Protection System every time you use heat shrink tubing from HellermannTyton


You are looking for the heat shrink tubing meeting your application requirements best?


This means HellermannTyton sets the pace with each new piece of heat shrink tubing when it comes to providing protection against mechanical, environmental, chemical or electrical effects.

我们欠我们的成功的关键因素是the unique and quite specific properties of our heat shrink tubing. Starting with the choice of material, for example, the different requirement demands raised by being used in the sensitive aerospace industry or rail transportation sector are focused on the self-extinguishing fire protection properties of heat shrink tubing.

According to the requirements set, the shrink ratio, that is to say the precise size to which heat shrink tubing is capable of shrinking, can be just as important in this process as dispensing with halogeneous materials in the manufacturing of heat shrink tubing.

What is heat shrink tubing?

Heat shrinking means:The process of applying heat,例如使用电或加热枪,shrink expanded plastic tubing or shapes down to its original size。A distinction is made in this respect betweenrecovered dimension(original size) andsupplied dimension(expanded size). Heat shrinking isused in various industries and applications– for instanceto insulate and protect电缆抵抗热,化学物质或水

Watch this video with our heat shrink experts Barry and Mark to see how easy heat shrink tubing is to handle.


每一块热缩管马tch its specific area of work to the highest degree of accuracy – from batch production, for example as the insulating handles of tools, to heat shrink tubing sleeves for maintaining underground cables which have already been laid and which would be extremely expensive to repair in terms of resources and costs without using corresponding specialised heat shrink tubing (heat shrink cable repair sleeves).


HellermannTyton provides workers and decision-makers involved in manufacturing with a solution fit to their specific needs, which is tailor-made for their specialist area or, in other words, every piece of HellermannTyton heat shrink tubing makes problems shrink, even before they arise.



热收缩管is extruded plastic tube that is expanded and will shrink back to its extruded size when heated. Heat shrink is used to electrically insulate cables and wires offering also mechanical and chemical protection.

Selection tools

Wall thickness of heat shrink tubing:

The material thickness will be indicated in mm after complete shrinkage. "Nominal" defines dimensions without any tolerances.
通常你可以区分薄壁,medium wall and thick wall heat shrink tubing.

Diameter of heat shrink tubing:

For thin wall tubing with a shrink ratio of 2:1 (standard tubing) the diameter is usually in inch sizes 25.4 mm equals 1 inch.

Shrink ratio:

Depending on the used compound material and wall thickness heat shrink tubing can be extruded to a different degree.
The shrink ratio indicates the rate, the product shrinks (supplied diameter in relation to recovered diameter). The shrink ratio varies from 2:1 to 6:1. The higher the shrink ratio, the more varying diameters of the object can be covered. Thus, fewer sizes of heat shrink tubings are needed. This helps to reduce stock and so requires less space.


热收缩管s do not shrink only in diameter, but generally also in length. This change in length after shrinking is indicated in a percentage

Minimum shrinkage temperature:

热收缩管s do not all shrink at the same temperature. It strongly depends on the type of compound they are made of and their wall thickness.

Operating Temperature:

The operating temperature varies per tubing type. This is dependent of the compound used for the tubing type

When selecting the correct heat shrink tubing size, it is recommended to follow the 80:20 rule.

In our application overview for heat shrink tubings you will find the recommended heat shrink tubing size for every cable diameter.
The 80:20 rule has of course been taken into account.

Note 1:For shrinking tubing it is advisable to start the shrinking process in the middle section of the tubing and then gradually proceed to one end and then from the middle again to the opposite end. Thus avoiding air becoming trapped under the tubing.

Note 2:热收缩管也将纵向收缩。切割管道时必须考虑这一点。

Note 3:It is possible to minimise the longitudinal shrink by shrinking the ends first and then the middle section.
However avoid air gets trapped and prevents the middle section from shrinking.
Alternatively the tubing should be shrunk down by starting at one, the most critical, end and shrinking down slowly towards the other end.

Note 4:If the object to be covered is metal or heat conductive care must be taken to ensure the object is pre-heated to avoid “cold spots” or “chill marks” so to ensure a tight and smooth fitting of the tubing.

Note 5:切割热管道并将其缠绕在袖子周围时,必须采取特殊护理,以确保平稳切割的末端。切割和不规则的边缘可能导致收缩管和袖子在收缩过程中分裂。

Note 6:When choosing the tubing size it is important to consider the 80 % / 20 % rule. This means the tubing size should be chosen to allow minimum shrinkage of 20 % and a maximum of 80 %. Discover a complete application overview in our product catalogue.

Note 7:During shrinking you should always make sure that the workplace is well ventilated.


Adhesive-lined tubing isalso known asdual-wall tubing。Because here you have a combination of a crosslinked outer jacket (Polyolefin) and an inner layer of adhesive. When heated,内部粘合墙融化和流动。这个过程创建了一个粘附层ensures a tight fit to the wire, cable or connector。Adhesive-lined heat shrink tubing is生产强大的天气密封件具有额外机械强度和极好的防御腐蚀的理想选择
