PP-R Aluminum Stable Static Pjpe is a kind of complex with PP-R and alloy aluminum. German called it PP-R Aluminum Stable Static Pipe, PP-R Reinforcement Pipe or PP-R Aluminum Stable Static Pipe adopt the normal size, PP-R Aluminum Stable Static Pipe adopt the technology of hot melted bind to bind its surface and alloy aluminum of 0. 15-0. 25mm width, and then covered PP-R or PE of 0. 2mm around for protection. it has five layers: polypropylene-glue-aluminum-glue-plypropylene. Aluminum words as the reinforcement agent and blend PP-R and metal. PP-R Aluminum Stable Static Pipe. After treatment, aluminum layer has stable machine characters of higher intensity and better anti-high temperature.
