What Is The Purpose Of Heat-Shrink Tubing?

Heat-shrink tubing is used across a wide variety of applications to insulate, protect, color-code, or provide strain relief for wire and cable.

Sealing

Heat-shrink tubing creates a tight seal around an electrical wire or connection. It provides excellent electrical insulation and protects the wire from abrasion, moisture and dust. Shrink tubing can be made from a wide variety of materials depending on the application and requirements of the product. Some of these materials include polyvinyl chloride (PVC) and polyolefin. PVC can be used for low temperature applications where the continuous high temperature is under 105 degC, but polyolefin is a better choice for continuous high temperatures of over 105 degC. There are also a number of different colors to choose from including black, clear and color-coded. Additionally, you can find diesel resistant tubing for use in applications that are exposed to harsh environments. When deciding on a shrink tube, it is important to understand all of your application requirements. This includes determining the correct size and shrink ratio for your application. This will help you to determine the best heat shrink tubing for your needs.

Strain Relief

Heat-shrink tubing provides strain relief to cables and wires. It is a convenient and cost-effective alternative to tie wraps and tape. There are several types of tubing to meet your requirements. The material used in the tubing and chemical makeup are key to selecting the right product for your application. Polyolefin and PVC tubing are the most common options for applications that don’t demand a great deal of durability. However, other materials are available as well, such as fabric, PTFE, and Kynar. These materials are geared towards environments that require superior abrasion and strength protection, such as automotive and industrial applications. They are also able to withstand a wide variety of chemicals and fluids. When choosing heat shrink tubing, ensure that the unshrunk diameter is at least 20% larger than the largest component to be covered. This will allow for proper positioning and ensure that the heat shrink will provide adequate insulation and strain relief.

Durability

Heat-shrink tubing provides a tough and durable surface to wires and cables. It’s ideal for a variety of applications, from motorhome electrical repairs to marine wire connections. The durability of heat-shrink tubing can be influenced by several factors. For example, the material chosen for the tubing can help determine its ability to withstand chemicals and other fluids in the environment. Another factor is the type of environment in which the cable or wire will be exposed. For example, if the wire will be in contact with water or other moisture, then it’s important to find a material that can resist water, oils, and grease.
