Insulated aluminum stretch tubing consists of aluminum and laminated layers of insulation cotton, and is reinforced with steel wire twisted into layers of aluminum foil and polyester.
Thermal insulated stretch aluminum tube conducts air circulation flexibly, withstands high temperatures, is elastic and very flexible. Consisting of aluminum and multiple layers of pressed cotton insulation, and reinforced with strong steel wire twisted into layers of aluminum foil and polyester. Using this technology, soft insulated air ducts are twisted with a continuous and multi-layer structure to create a flexible air circulation duct that can withstand high temperatures.
