Pexb-anUV has two layers, the material of its internal layer is silicane crosslinked polyethylene, the white one ,green environment, has the capacity of heat-resistance for a long time and aging resistance with innocuity as well as corrosion resistance.And the external layer , black one,mix with polyethylene,carton black and oxidation inhibitor,has the excellent capacity of ultraviolet radiation resistance , Compared with current common metal pipes, it is more heat-preservation and energy-saving. Therefore, it will be a new type of pipe with benefit to environmental protection.
