| PEXb-anUV, 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 esistance with innocuity as well as corrosion resistance. And the external layer, black one, mix with polyethylene, carbon 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. | ||
