What role does shrink ratio play in selecting the right Heat Shrink Insulation Tube?

The shrink ratio determines how much a heat shrink tube contracts when heated, affecting its ability to fit different cable sizes. Common ratios include 2:1, 3:1, and 4:1. A higher shrink ratio allows a single tube size to meet a wider range of applications, making installation more flexible and reducing inventory complexity. Selecting the right shrink ratio ensures proper sealing, insulation, and mechanical protection of wires and connectors.

In South America, installers often handle cables of mixed sizes and encounter non-standard wiring practices, especially in construction, repair work, and automotive applications. As a result, they require tubing with reliable and versatile shrink performance. Many importers report issues such as tubes that do not shrink evenly or fail to achieve the expected final dimension. This inconsistency leads to poor sealing, moisture ingress, and increased maintenance costs for end users.
