Product Overview
 

Saneper PEX-b/AL/PEX-b aluminum-plastic composite pipe is compounded by extrusion method, whose middle layer is butt welding or butt welding aluminum belt, and its internal and external layer is silane cross-linked polyethylene (PEXb) raw materials, with specialized hot melt adhesive adopted among the layers. Because silane is euhedral structure, whose ---och3 atom cluster in three points can participate in the reaction, namely, whose---och3 atom cluster can be connected with the long chain of polyethylene molecules, its reaction product is three-dimensional network structure, which enables that its comprehensive performance of physical mechanical strength is relatively good and the creeping possibility is low. The Si-O-Si molecular bridge exists among polyethylene molecular chain, but not the C---C molecular bridge, thus it’s not susceptible to oxidation and has high thermo-oxidative stability. Because it’s multi-point and three-dimensional cross-linking, its cross-linking density is much higher than that of peroxide cross-linking product (PEXa) under the same cross-linking degree, which greatly enhances its resistance to pressure in high temperature.
