Heat shrink can be found in an array of materials that suit virtually any application. It has several useful applications, including providing electrical insulation for wires, splices, terminals, joints, connections, and bundling loose items including wires and used as a protective covering.
Heat shrink tubing hit the market in the 1950s. It was created by the Raychem Corporations engineer founder Paul Cook. He made use of radiation chemistry (which is what the company is named for) to create the two main products the company is best known for:
Along with these polymers, some special-application heat shrink also includes an adhesive lining that assists in bonding the tubing to the underlying connectors and cables. This creates strong seals that are often waterproof.
Another material often added to some types of heat shrink tubing is a thick, conductive polymer film. This offers an electrical connection between the conductive objects being connected. With this method, no soldering is necessary.
As mentioned above, polyolefin is the most common material used for heat shrink tubing. The advantages offered by this include the cross-linking of the polymer chains. This allows it to withstand higher temperatures.
If your needs for heat shrink tubing involve an environment where the continuous high temperature is under 105 degrees Celsius, you should consider using PVC. Along with the more affordable prices offered by PVC, it also provides you with colors that are more vibrant than polyolefin and better clarity.
A higher shrink ratio is going to let the sleeve fit over bigger objects, such as connectors. Once in place, the tubing is shrunk to the smaller diameter of the cable. However, a general rule of thumb is to never use a higher ratio than the application demands.
Each sleeve available has a different degree of flexibility. Sleeves that are more rigid are a good choice to achieve strain relief for terminals or connectors. Here, reducing flexing is a goal of the heat shrink tubing.
Some tubing includes a meltable or adhesive inner layer for applications that demand superior sealing levels. In most situations, standard tubing will provide plenty of sealing, but the adhesive lined tubing takes this a step further.
The most common way to shrink heat shrink tubing onto something is by using a small, hand-held heat gun. However, if you have higher volumes, the preferred method for shrinking the tubing is a flow-through oven.
Heat shrink tubing is a type of protective electrical insulation tubing that activates and shrinks when the heat is applied. Shrink tube is most commonly used in the insulation protection of cables, wires, joints, and terminals due to its durable exterior and tight fit. Heat shrinkable tubing is preferred to other electrical insulation tubing due to heat shrink's ability to mold around the shape of the cable or wire connection point. Therefore, protecting against various environmental strains and abrasions. While all types of heat shrink tubing generally serve the same function, different needs require different shrinkable tubing. Due to the vast array of cable and hose diameters, heat shrink is produced in various sizes, thicknesses, and materials. Depending on the desired use, and it is helpful to understand which shrink tubing materials are best for your particular needs. Cabletiesandmore boasts the largest Online selection of heat shrink tubing for sale. We provide a wide variety of heat shrink tubing that is in stock, depending on your specific situation.
The first feature to think about is the size. How big are the wires, cables, or general devices you wish to use with shrink tubing? 2:1 heat shrink tubing shrinks to half of its original size. 3:1 heat shrink tubing will shrink to a ratio of one-third of its original size, and 4:1 heat shrink tubing will shrink to one-quarter of its original size. You will want to pick a sizeable heat shrink diameter that is bigger than your largest measurement but will shrink to fit your smallest measurement snugly.
Next, you will want to determine the best material for your heat shrink tubing. As mentioned, different shrink sleeves are needed for different circumstances. When deciding what heat shrink to use for an industrial application, you may choose to use our 2:1 High Temp Viton Heat Shrink Tubing or diesel resistant heat shrink due to their powerful chemical resistance.
2:1 Polyolefin Heat Shrink is the standard for heat shrink tubing material because of its overall temperature and chemical resistance, commonly used for cable management when bundling and insulating of wires. For protection against moisture, dual wall adhesive lined heat shrink sleeving provides a water-proof seal. Alternatively, fabric heat shrink sleeving uses a unique blend of Polyolefin and Polyester yarns to resist trapping water and humidity. Kynar heat shrink tubing provides the ultimate heat resistance and flexibility, making it ideal for small spaces like fuse coverings. Neoprene heat shrink is a popular choice for military and aerospace applications because neoprene is flame-retardant and is also highly resistant to lubricating oils and hydraulic fluids. However, diesel resistant heat shrink tubing is also a suitable choice. We also provide different colors of heat shrink tubing for identification purposes, as well as customizable heat shrink tubes if you would like specific lettering or wording.
Ensure that heat shrink tubing is applicable for your intended use. variable temp heat guns and butane torches are efficient and effective, providing the maximum heat necessary for proper shrinkage. You will likely want to find one that is handheld and easy to use, but make sure to use the appropriate temperature range depending on your shrink tubing. Remember, different materials can withstand different heat levels!
adhesive-lined heat shrink wrap tape instead. Some applications may not be able to fit through shrink tubing, making heat shrink tape a better choice. It provides the necessary bonding and protection with added flexibility and versatility. Here at cable ties and more, we carry a wide selection of heat shrink tubing and heat shrink accessories for your unique needs
Before installing heat shrink tubing, you should educate yourself on how to shrink heat shrink. There are more than a few ways that heat shrink tubing can be shrunk to its recovered size. However, to properly install heat shrink begins by feeding the cable or hose inside the opening of the heat shrink either by hand or using an electrical wire fish rod to get the tubing to the end of the run. Once the heat shrink fully encloses the wire or hose, you can start applying high heat from Heat tools. Finally, sit back and watch as the shrink tube recovers down to a snug fit on the cable or hose that is now insulated internally.
Heat shrink tubing, also known as heat shrink sleeving, is a specially designed casing that is widely used for the insulation and corrosion protection of various wiring harnesses, solder joints and components. It is also excellent for minor repairs of cables and connectors. However, before selecting the appropriate heat shrink tubing for a specific application, it is vital to understand the characteristics and the key parameters of this product.
There are various sizes of heat shrink tubing available on the market, so how do you select the most appropriate product? By making an informed decision utilizing the various parametric options for heat shrink tubing on the Digi-Key website.
A high shrinkage ratio means that the heat shrink tubing is more suitable for objects like connectors as it can encase the connector body and still be able to shrink down to a smaller diameter such as a wire or cable. In general, it is recommended that the supplied inner diameter of the heat shrink tubing and the size of the object to be protected should not exceed a 40% ratio to allow for effective coverage.
The material heat shrink tubing is made from denotes its features. For example, PTFE (polytetrafluoroethylene) tubing is characterized by resistance to flame and chemicals, and has an operating temperature of 260˚C.
Heat shrink tubing is an essential tool to protect and enhance your wiring projects. As a shrinkable plastic covering, it is used to insulate and protect wires, conductors, and terminals from moisture, wear and tear, and abrasion. It can also be a great branding opportunity.
