Perforated Aluminum Strip for PP-R Steady-state Tube
Using hot melt bonding technology, the outer surface is organically bonded to the aluminum tape with a thickness of 0.15/0.12mm at high temperatures. Perforated Aluminum Strip for PP-R.
Steady-state Tube has a five-layer structure of polypropylene-glue-aluminum-glue-polypropylene, and the middle aluminum layer plays a reinforcing role, which organically combines PP-R plastic and metal and keeps the flexibility of plastic pipe and the rigidity of metal pipe.
Product specification
1. Small coefficient of linear expansion, high-temperature resistance, no deformation
2. Impermeable to oxygen, can inhibit the growth of algae bacteria, more hygienic
3. Aluminum layer can effectively block UV rays and have a longer service life
4. The aluminum layer is more pressure-resistant and stable for the pipeline and reduces creep.
5. Hot melt connection, no leakage
