Heat shrink indication
- When shrinking the heat-shrinking sleeve, use equipment made for this specific operation such as, for example, guns or hot air tunnels.
- Shrink the sleeve starting at one end, the most critical part, and then proceed slowly to the opposite end. This method avoids the formation of air bubbles between the inner wall of the heat shrink sleeve and the object it covers.
- In the event that the object to be covered is made of metal or a good heat conductor, it is advisable to preheat the object to avoid “cold areas”, so as to allow a perfect and soft adaptation of the heat-shrinking sleeve.
- In order to avoid overheating of the heat shrink sleeve, ensure a regular heat distribution. Excessive overheating of the material during the shrinking process can cause bubbling, discoloration and in some cases even breakage of the heat shrink sleeve.
