Features of Product:
New type stable PPR pipe extrusion line is a new generation line developed by adopting updated German technology, it overcomes the defects of common PP-R pipes such as high expansion coefficient, bad anti tardily variation, very easy to deform. Inner layer of pipe products is the common pipe extruded, after it is coated with aluminum foil, then coated by a PP-R out layer, the foil layer is sticking on plastic layer with hot-melt glue.
Production is made up of PP-R inner layer molding unit, aluminum foil molding, glue coating unit and out PP-R extrusion molding unitetc. The products have the characteristic such as anti high temperature, easy joining and small thermal expan-sioncoeffcient, powerful anti press intensity, antiultraviolet radiation, good antistrike at low temperature, which expand the application range for common PP-R. This line can' t only produce stable PP-R pipe, but also the common pipe.
