1. Healthy and non-toxic, free of stain and scale
2. High temperature resistance (maximum water temperature up to 90 degree) and high pressure resistance (over 5MPa)
3. Excellent heat insulation property from minimum thermal conductivity (only one hundredth of that of metal pipes)
4. Light weight (approximately one eighth of that of metal pipes), easy to handle and transport
5. Smooth inner wall, reducing the pressure loss and increasing the flow speed
6. Couleurs douces et excellent design, convient pour une installation exposée ou cachée
7. Wonderful ability in chemical corrosion resistance.
