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?
Areas where heat shrink tubing is used vary greatly. This is why HellermannTyton focuses on matching all of its heat shrink tubing optimally in the jobs for which it will be used in developing, manufacturing and distributing its heat shrink tubing and heat shrink moulded shapes.
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.
The key factors to which we owe our success are 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.
Every single piece of heat shrink tubing has to match 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).
From adhesive lined heat shrink tubing to transparent heat shrink tubing which allows the identifying elements to remain visible on cables to be insulated, HellermannTyton offers a comprehensive range of heat shrink tubing products that meets the highest international standards.
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.
Heat shrink tubing fitting your requirement best!
Heat shrink tubing 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.
HellermannTyton is a global manufacturer who offers high performance fastening, connecting, routing, protecting, and identifying solutions to diverse markets. For our customers we develop market solutions that uniquely meet industry needs - solving an application requirement, saving installation and component costs, and improving the quality of the end product - no matter what your industry:

HEV Cable Breakout Boots
Cable breakout boots are designed for insulating and sealing a cable crotch, or conduit system, and provide excellent resistance to abrasion and weathering.
SGP Grade Flame-retardent Polyolefin General Purpose Heat Shrink Tubing
SGP General purpose heat shrink tubing is a cost effective product for numerous commercial insulation applications. It provides effective electrical insulation and protection for in-line components, disconnect terminals and splices. It also bundles wires and cables for very flexible lightduty harnesses, use as strain-relieves for electrical wire connections and colour-codes wires, cables, terminals and components.

Powerful, electronically controlled hot air guns with temperature control and cool air stage for dedicated DIY enthusiasts and frequent users. HellermannTyton offers the HL1610S, HL1910E and HG2000E Hot Air Gun.
Wall thickness of heat shrink tubing:
The material thickness will be indicated in mm after complete shrinkage. "Nominal" defines dimensions without any tolerances.
Generally you can distinguish between thin wall, medium wall and thick wall heat shrink tubing.
Heat shrink tubings are also available with adhesive liner. They are also called dual 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.
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.
Longitudinal change after shrinkage:
Heat shrink tubings 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:
Heat shrink tubings do not all shrink at the same temperature. It strongly depends on the type of compound they are made of and their wall thickness.
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.
Heat shrink tubing should shrink by at least 20% and not more than 80% of the supplied diameter to achieve the optimal result.
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.
Heat shrink tubings are used for cable harness assembly in general. The application of heat shrink tubings covers insulation, cable identification and, besides esthetical reasons, mechanical protection as well.

Application guidelines for heat shrink tubings
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: Heat shrink tubing will also shrink longitudinally. This has to be considered when cutting the tubing.
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: When cutting heat shrink tubing and wrap around sleeves to the desired length special care has to be taken to ensure smoothly cut ends. Poorly cut and irregular edges can cause heat shrink tubing and sleeves to split during shrinkage.
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.
