Adhesive lined heat shrink tubing, generally well-known as glue lined tubing, has almost all the benefits of conventional heat shrink but with one other significant feature; a coating of adhesive made of thermoplastic. Outer tubing made of Polyolefin and an inner lining with hot melt adhesive go into making the best glue lined end caps that offers better seal as well as adhesion. Not many products are a good solution for protection and sealing of cable ends and shield them from environmental damage.

Depending on the area the pipes will be applied at, these end caps come in a range of forms. But, the special properties inbuilt in Adhesive lined head shrink make it a better choice for some applications plus a few environments than the normal tubing. First of all, it is very much thicker in size than standard heat shrink. Evidently this rules it out from being applied in more exact applications, but also indicates it offers a safe and more enduring means of providing insulation to heavier cables. Certainly it is far less elastic than the regular head shrink, and due to this inflexibility, it won't wind around with wires like heat shrink that are smaller in size. Yet again, this strengthens its application in heavy electrical installations.

Adhesive lined heat shrink tubing does hold up well in some environments and is broadly used in naval applications. As a result of its better sealant properties, it is perfect for insulating as well as sealing electrical also mechanical components against moisture. From the point of moisture resistance, it's also just the thing for efficient insulation of electrical connections in addition to splices. For example, while fixing electrical equipment on a vessel, a butt connector is frequently used. These connectors facilitate current flow and guard against rust but also use Adhesive lined heat shrink tubing to stop the water. And this robust tubing also has a new advantage of lessening the intensity of heavy mechanical strain.

Standard heat shrink tubing has different applications. For one, they are used to shield wires, joints, and connections in several industries but user more extensively in the military and aviation. On the other hand, Adhesive lined head shrink end caps are used to seal the ends of rubber, plastic, and paper insulated cables from dirt, moisture and corrosion. Normally resistant to most of the fluids as well as chemicals, Adhesive lined head shrink end caps can be applied on cables at a fairly normal degree of internal pressure particularly at a temperature between -30 and 70 degrees. They don’t lose any of their magical properties even when subjected to extreme temperature which is why they are having a lot of applications.

When you are out there on the market to buy this sort of heat shrink tubing, you are most likely to find them sorted according to their shrink ratios. Note that shrinking occurs only on the diameter of the tubing whereas the length remains unchanged. For example, PTFE tubing with a shrink ratio of 2:1 would go through contraction, shrinking to half of its actual dimension. Speaking of categories, there are three different types namely thin wall tubing, thick wall tubing as well as medium wall tubing.
