The products that are referred to as heat shrink tubes’ can be an essential accessory for many industrial applications. It’s a product that helps protect the electrically insulate and bundle cables and also provides an environmental seal to prevent contamination of any kind from harming the sensitive components. The process of creating this item is an interesting one, and the short description below will help you understand it.
How is Extruded Tubing transformed into a heat-shrinkable material?
The process of making polyolefin or PVC tubing that is heat shrinkable can be accomplished after the initial extrusion has been completed. The force is applied under the conditions of very high temperatures to increase the diameter of the tubing. The tubing remains solid at this new dimension; however, it shrinks back to its original extruded dimensions upon application of heat using an air gun. The application of heat can be accomplished using an oven or another source of thermal energy. In this method, however, the primary role is determined by the shrink rate of the tube. The shrink ratio ranges between 2:1, 2.5:1, 3:4, or 4:1 and decides the extent to which the tubing shrinks upon the application of heat. For instance, a shrink ratio of 3:1 signifies it will reduce the size of the tubing by 1/3 of its initial diameter. Certain manufacturers offer custom-designed shrink ratios that meet the specific specifications of their customers. In some cases, heat shrink tubes are equipped with an adhesive layer on the interiors, which melts when heated and allows it to be fitted snugly over the electrical part acting as a watertight seal. Alongside the diameter shrinkage, there is also a longitudinal shrinkage. However, this is not significant relative to circular shrinkage.
Use of a variety of materials
Polyolefin, as well as PVC, is the most commonly used substance to make the tubing. The main factors that influence their use are the price and the temperatures, which must be complied with during the process. For instance, an automobile’s interiors and instrument panels utilize PVC tubing, whereas the engine will require polyolefin tubing. The more excellent temperature range is offered to the polyolefin tube by the thermoset material, which goes into its production. PVC tubing, however, is made of thermoplastic materials.
Electrical & Other Application
Tubes for heat shrinking are used in many different applications but are most often used for wiring harnesses. They are utilized for bundling loose cables or for providing strain relief. They shield cables from chipping, cutting, peeling, or dents, in addition to protecting them from any damage. They come in vibrant colors and thus are utilized for applications that require ‘glow-in-the-dark or neon colors or in cases where the user is worried about the design of the cables. Color code is made possible through the making use of these tubes. Additionally, occasionally they can be helpful in providing information about models, the company logo names or contact numbers, and the date of manufacture, as well as instructions to use and safety precautions.
The entire range of cable accessories such as heat shrink tubes, as well as others like 36KV cable joint, transition joints, heat shrink boots, etc., are an asset for the industrial industry.
