PE Composited Insulation Tube Series are a highly effective insulation material made from closed-cell foamed polyethylene, primarily used in heating, ventilation, and air conditioning (HVAC) systems, as well as in refrigeration and air conditioning systems. These insulating tubes typically have a multilayer structure (usually including an outer layer with a rough, weather-resistant surface) and are used to cover copper or aluminum pipes to prevent condensation and reduce heat loss.

^{PE Composited Insulation Tube Series}

Our embossed polyethylene insulation sleeves feature a three-layer structure: the outer layer is embossed, providing a smooth, attractive surface, and is resistant to aging and ultraviolet rays; the inner layer consists of closed-cell foam, manufactured using a unique formula, which has excellent thermal insulation properties and retains its shape at temperatures up to 95 °C; This insulation sleeve consists of two assembled tubes, ensuring easy disassembly, convenient installation, and an attractive appearance. When used with copper or copper-aluminum pipes, they are the optimal choice for connecting the indoor and outdoor units of air conditioners.

These sleeves are made of closed-cell polyethylene (PE), have no seams or cracks, feature low water absorption and excellent thermal insulation properties, and do not cause corrosion of steel and copper pipes. The surface of the sleeve can be coated with a layer of embossed polyethylene. These sleeves are widely used as insulation sleeves for air conditioners and as protective sleeves for metal pipes.
