DOMADIA Thin Walled Heat Shrink Tubings / Sleevings
DOMADIA Heat shrink sleeving or tubing is a type of material that shrinks in size when exposed to heat. It is commonly used for insulation, protection, and bundling of wires, cables, and other components. When heat is applied to the sleeving or tubing, it conforms to the shape of the object it is covering, providing a tight and secure fit.
Heat shrink sleeving or tubing is typically made of polymer materials such as polyolefin, PVC, or fluoropolymers. These materials have excellent electrical insulation properties, as well as resistance to heat, chemicals, and abrasion.
The process of using heat shrink sleeving or tubing involves sliding the sleeving over the object to be covered and then applying heat using a heat gun or other heat source. As the heat is applied, the sleeving shrinks in size, tightly encapsulating the object.
There are different types of heat shrink sleeving or tubing available, each with its own characteristics and applications. Some common types include:
Thin-Wall Heat Shrink Tubing: This type of tubing has a thin wall and is suitable for applications where space is limited. It provides good electrical insulation and mechanical protection.
Heat shrink sleeving or tubing is widely used in industries such as electronics, automotive, aerospace, telecommunications, and construction. It is an effective solution for insulating and protecting wires and cables from environmental factors, preventing abrasion and damage, and ensuring the longevity and reliability of electrical connections.
Multiple layers of thin-wall heat shrink tubing can be used to achieve a higher covering thickness or provide additional insulation and protection. By applying multiple layers of tubing over the desired area, the combined thickness of the layers increases, providing enhanced insulation properties and mechanical protection.
Using multiple layers of heat shrink tubing can be beneficial in situations where the standard thin-wall tubing does not offer sufficient insulation or where added durability is required. It allows for customization and flexibility in achieving the desired level of protection based on specific application requirements.
When applying multiple layers of heat shrink tubing, it is important to ensure proper sizing and compatibility between the tubing layers. The outer layer should have a larger diameter than the inner layer to accommodate the additional thickness.
Additionally, it’s important to consider the heat shrink ratio of the tubing when using multiple layers. The heat shrink ratio indicates how much the tubing will shrink when heated. If you plan to use multiple layers, ensure that the tubing has a sufficient shrink ratio to accommodate the cumulative thickness of the layers.
By using multiple layers of thin-wall heat shrink tubing, you can achieve a thicker and more robust insulation and protection solution for various applications, such as high-voltage cables, heavy-duty wiring, or environments with harsh conditions

History:
Polyolefin heat shrink sleeves have a relatively recent history compared to other types of heat shrink materials. Here’s a brief overview of their development:
Polyolefins are a group of polymers that include polyethylene (PE) and polypropylene (PP). These materials possess excellent electrical insulation properties, high chemical resistance, and good mechanical strength. They are widely used in various applications, including packaging, automotive components, and electrical insulation.
The development of polyolefin heat shrink sleeves can be traced back to advancements in heat shrink technology in the mid-20th century. The ability of polyolefins to shrink when exposed to heat made them a suitable choice for heat shrink applications.
In the 1960s, the first polyolefin heat shrink sleeves were introduced primarily for electrical insulation purposes. They provided a simple and effective solution for insulating and protecting electrical connections, wires, and cables. The sleeves were designed to shrink tightly around the objects when heated, creating a secure and durable insulation barrier.
Over time, the manufacturing processes and formulations for polyolefin heat shrink sleeves were refined, leading to improved performance and expanded applications. The development of cross-linking technology further enhanced the properties of polyolefin materials, allowing for increased mechanical strength, higher temperature resistance, and improved resistance to chemicals and environmental factors.
Polyolefin heat shrink sleeves gained popularity in various industries, including telecommunications, automotive, aerospace, and construction. They were used for cable and wire harness insulation, splice protection, corrosion prevention, and identification purposes.
With the introduction of different types and grades of polyolefin materials, such as low-density polyethylene (LDPE) and high-density polyethylene (HDPE), as well as advancements in manufacturing techniques, polyolefin heat shrink sleeves became more versatile and adaptable to a wide range of applications.
Today, polyolefin heat shrink sleeves are widely available in various sizes, colors, shrink ratios, and wall thicknesses to suit different requirements. They continue to be an essential component in electrical and mechanical systems, providing reliable insulation, protection, and organization of wires, cables, and components.
