Heat Shrinking guidelines

For shrinking the heat shrink tubing, use equipment specifically designed for this operation, such as heat guns or hot air tunnels.
Start shrinking from one end-preferably the most critical point—and then proceed gradually toward the opposite end. This method helps prevent the formation of air pockets between the inner wall of the tubing and the substrate.
If the substrate is metal or a good thermal conductor, preheating is recommended to avoid “cold spots” and ensure a smooth, uniform recovery of the tubing.
To prevent overheating, ensure even heat distribution throughout the process. Excessive overheating may cause bubbling, discoloration, or, in some cases, damage or rupture of the tubing.
