The Difference Between Heat Shrinkable Dual-wall tubes and Medium-wall tubes

Heat Shrinkable Dual-wall tubes:

Heat Shrinkable Dual-wall tubes consist of two layers of heat shrink tubing, an inner layer of adhesive-lined polyolefin and an outer layer of heat shrinkable polyolefin. The inner layer of adhesive provides an air and water-tight seal, while the outer layer provides insulation and mechanical protection.

Heat Shrinkable Dual-wall tubes are designed to be used in harsh environments or where the cable is exposed to moisture, chemicals, abrasion, or extreme temperatures. Because of their excellent sealing and insulation features, they are typically used in low and medium voltage applications, such as automotive, telecommunications, and aerospace industries.

Heat Shrinkable Medium-wall tubes:

Heat Shrinkable Medium-wall tubes are a single layer of heat shrink tubing, with a thickness of around 2-3 mm. They provide high levels of insulation, mechanical protection, and environmental resistance. Unlike Dual-wall tubes, there is no inner adhesive lining in Medium-wall tubes.

Heat Shrinkable Medium-wall tubes are typically used in medium and high voltage applications, such as power distribution and transmission systems. They are designed to offer reliable insulation and strain relief to cables and connector joints that are subjected to stress and harsh environmental conditions.

So, the main difference between Heat Shrinkable Dual-wall tubes and Heat Shrinkable Medium-wall tubes is that Dual-wall tubes have two layers, an inner adhesive layer and an outer insulation layer, while Medium-wall tubes have a single layer of insulation and provide mechanical protection.
