plastic machinery PP-R aluminum stable static pipe is a kind of complex with PP-R and alloy aluminum. Germans call it PP-R aluminum stable static pipe, PP-R reinforcement pipe or PP-R inner aluminum pipe. On the basis of the normal size, PP-R aluminum stable static pipe adopts the technology of hot melted binding to bind its surface and alloy aluminum of 0.15-0.25mm width, and then covered with PP-R or PE of 0.2mm around for protection. It has five layers: polypropylene-glue-aluminum-glue-polypropylene. Aluminum works as the reinforcement agent and blends PP-R and metal. PP-R aluminum stable static pipe has the flexibility of plastic pipes and the horniness of metal pipes at the same time. After treatment, aluminum layer has stable machine characters of higher intensity and better anti-high temperature performance.
