Did you know there are heat shrinkable caps?

Conclusion: Heat shrink caps can be used for a variety of purposes, including waterproofing and protection, preventing water and oil leaks and corrosion, and insulation .

In this article, we will introduce the features, benefits, and use cases of heat-shrinkable caps.

1 What is a heat shrink cap?

As the name suggests, heat shrink caps are caps that shrink in size when heat is applied.
Heat shrink tubing is hollow and cannot be used to hold down the tip.
On the other hand, heat shrink caps are molded to completely seal the tip, allowing them to be used for purposes other than tubing.
Insulating caps made of materials such as PVC are common, but heat shrink caps can be adjusted in size using heat to fit tightly to the object being covered.

There are three ways to make a heat shrink cap.
1. Extrusion molding into a tube shape, then sealing the tip 2. Inflating the cap shape using a technique called blow molding Our heat shrink caps are manufactured using blow molding, which provides high airtightness and protection.

It is widely used in a variety of fields due to its high airtightness, insulating and waterproof properties.

2. Specific usage of heat shrink caps [Waterproof]

Heat shrink caps are not simply caps that shrink when heated.

The inside of this cap is coated with hot melt adhesive (glue) that melts when heated.

By placing it over the object to be coated and applying heat, the cap shrinks and the hot melt melts, filling in the gap between the object to be coated and the cap.

It can be used for waterproofing purposes by attaching it to areas where moisture is present outdoors or inside equipment.

3. Specific usage of heat shrink caps [protection]

Heat shrink caps can also be used to protect the tips of protruding objects.
It is also used to protect and secure the ends of objects other than electrical wiring, such as mounting frames, metal pipes, and timber.
Both the tube and the hot melt can be removed cleanly after use by making a cut with a cutter or similar tool, without leaving any stickiness behind.

4. Specific usage of heat shrink caps [oil and water leakage prevention]

Heat shrink caps are also used to prevent oil and water leaks, taking advantage of the waterproofing properties introduced in 1.
It can be used as a temporary catch basin for oil leaks, water leaks, etc. by covering the tip.

However, there is no specific data on pressure resistance.
Please refrain from using this product as a complete measure against oil and water leaks.

5Specific ways to use heat shrink caps [Corrosion prevention measures]

Heat shrink caps are also used to prevent corrosion of metal products, taking advantage of their waterproof properties and shape.
Specifically, it is used by covering bolts, nuts, etc.

6. Specific uses of heat shrink caps [Insulation]

Polyolefin heat shrink caps are naturally insulating as well.

Instead of covering the blocked terminal or insulating with vinyl tape,

It can also be used as an insulating material.

summary

It can be easily installed even in cases where installation would be difficult using heat shrink tubing.
