Heat Shrink Sleeve is a type of tubing that can be used to package wires, cables, and other small components together in a single confined space. It's a great way to "beef up" a cable assembly and increase the life of the unit by protecting the components from harsh conditions.

When choosing a heat shrink tube, consider several factors such as the application, material properties, operating temperature, and shrinkage temperature. These factors are necessary to ensure that the sleeve will work well in your particular environment.

The most common materials for heat-shrinking tubing are polyolefin and PVC. These are both durable and strong materials with excellent flexibility and fire resistance qualities. They are also inexpensive, so they're a great choice for low-temperature applications.

Polyolefin: This is one of the most popular and commonly chosen materials for heat-shrinkable sleeving because it offers a wide range of benefits, including excellent insulation and protection from temperature swings, moisture, and abrasion. It can be manufactured with various colors and is a flexible option for use in tight spaces.

PVC: It's cheaper than polyolefin and offers good insulating qualities while retaining its high level of durability. It's available in a variety of different color options and can be produced with a thick layer of adhesive for added support.

The sleeving itself is made from an extruded sheet of polyolefin, which is then exposed to electron irradiation to cross-link the material and improve its molecular structure. This allows the material to shrink when heated and recover to its original shape when it cools down again.

During the irradiation process, the polyolefin's chemical bonds are altered, and a new chemical bond is formed. This new bond helps to provide the plastic memory that the sleeving will need to shrink back to its original size. This process is often referred to as "extrusion and irradiation." 

The sleeve can then be heated and expanded in either a continuous or discrete manner. For large, thin-walled sleeving, the discrete expander is recommended because it reduces the potential for damage to the walls of the sleeve during expansion.

A heat-shrinkable sleeve is a special type of sleeving that has been specially formulated to be able to stretch and expand under stress. The sleeve begins with a thick extruded poly olefin sheet, which is then exposed to electron irradiation. This process cross-links the poly olefin and alters its molecular structure, making it more robust and resilient to stress.

This method also makes the sleeve more pliable and withstands the rigors of transport. The sleeve can be easily shaped and molded into a variety of shapes.

There are many types of heat-shrinkable tubing, each with their own set of benefits. They all have their pros and cons, which means that the ideal material for a given project depends on the needs of the product. It's important to find a partner that can help you optimize your design for manufacturability. This can include requesting samples from their work to compare to your specific requirements.
