Polypropylene pipes for building water supply
1. Indoors draining for high buildings, hospitals, hotels, schools and healthy apartments and so on which have high standard limit for environmental noise,
Industrial pollution and discharge.
2. The polypropylene of the inner layer has strong resistance to hot water, corrosive liquid and mechanical bruise. Because of the smooth inner surface, it can avoid being coagulated with dirt and reduce noise when draining.
3. The character-changed sticky and elastic material of PP-m is adopted in the MID-layer to strengthen the intensity of the pipe material, playing the key role of excellent voice-absorbing performance and giving good rigidity to the pipe material
4. For the outer layer, we adopt high concussion intensity endurable polypropylene material; It has good climate-resisting ability. This kind of outer protection layers is very firm with smooth surface and representative color of blue-gray.
