Heat shrink tubing is currently a major product for pipeline weld corrosion prevention, rigid-plastic transition corrosion prevention, and gas pipeline wall penetration corrosion prevention. Many manufacturers exist in China; however, how much does the price actually vary? In fact, the market price of heat shrink tubing is not significantly different, mainly due to the following three reasons:

First, the market price of raw materials for heat shrink tubing is basically uniform, unless some manufacturers use recycled materials.

Second, the processes for producing heat shrink tubing are largely the same. They all must go through several production processes, including extrusion, irradiation, expansion, gluing, trimming, printing, and packaging. This makes the production efficiency of heat shrink tubing lower than that of heat shrink tape, because heat shrink tape is stretched and expanded during extrusion.

Third, the rising cost of labor in China is also significant, and there is not much difference. Therefore, for a qualified heat shrink tube, the market price is not significantly different. If there is a large price difference, we need to be cautious when purchasing.
