LDPE Foam Air Conditioning Insulation Pipe
Our embossed PE insulation sleeve tube has three-layer structure: Outer layer embossing process is smooth, beautiful, anti-aging, anti-ultraviolet; Inner layer is independent foam with bubble structure, unique formula, good insulation resistance, resistance to high temperature of 95 degree without deformation; The insulation sleeve tube is twin-tube combination and easy separation, easy installation, beautiful appearance. Installed with copper tube or Cu-Al tube it is the best choice for connecting indoor and outdoor of air conditioners.
This sleeve tube is made of polyethylene(PE) closed-cell foam, the tube has no interface cracks with small water absorption and good insulation properties, and does not corrode steel tube and copper tube. The surface of sleeve tube can be fixed with a layer of embossed Pe sheet. This sleeve tubes can be widely used for air conditioning insulation pipe and protective sleeve of metal pipes.
