Heat shrink tubing, also called electrical shrink tubing, is a plastic tubing piece designed to provide a protective layer around multiple wire arrays and electrical devices and contract upon heat exposure. These thermoplastic tubes readily collapse to fit various equipment’s contours for covering single wires or wire bundles to protect them against cuts, moisture, abrasion, and dust in various settings.
Furthermore, they also insulate electrical components, thus preventing them from environmental damage and even failure. They come as colour-coded electrical shrink tubing that allows easy identification. The tubing is constructed from durable thermoplastic materials with easy installation. Additionally, these electrical and thermal insulators also bind connectors, wires, terminals, joints, and splices together for manageable bundles.
Key Benefits of Heat Shrink Tubing:
Heat shrink tubing provides a bunch of unique benefits, including:
- They are easy to use with a smoother and finished appearance.
- Provides robust thermal and electrical insulation with enhanced structural support.
- Safeguard against sharp-cutting edges, abrasion, chemicals, water, dust, and low impacts.
- Easy wire organisation for less strain on wires and other components.
- Easy wire identification and compatibility option due to colour additives.
- Made from highly thermoplastic materials for robust sealing and insulation applications.
Materials of Heat Shrink Tubing:
The operational conditions of bespoke tubing determine the material types for bespoke tubing for their robust functionalities. Besides highly thermoplastic materials, other heat shrink tubing materials include PVC, polyolefin, adhesive-lined polyolefin, PTFE, FEP, silicone rubber, and elastomers.
How Can I Install Heat Shrink Tubing?
It is simple to install electrical shrink tubing; however, the maximum and minimum diameters of the device to be covered should be determined when choosing the right tubing size. For effective and neat installation, cut the tubing to the desired length with scissors, which then easily slide over the object to be covered. Use a handheld heat gun or shrink oven to tighten the shrink. Before heating the tube, it is recommended to verify the desired heating temperature of the tubing to avoid overheating and uneven shrinkage.
Typical Heat Shrink Tubing Applications:
Due to the shrink tube’s versatile nature, it is widely used in industrial, electrical, and telecommunication settings, offering multiple functions, such as:
- Electrical insulation for covering joints and repairs.
- Strain relief applications for relieving pressure from various cabling.
- Colour coding for wire and component identifications.
- Wire bundling and mechanical and environmental protection for protecting cables from moisture, abrasion, chemicals, and dust.
