UV Resistant PP-R Pipes: Built to resist Sunlight 

Suitable for: Potable water (H&C) Heating Cooling Irrigation

Audited UV-resistance: The resistance of POLYMELT UV system against UV-radiation was tested by an accredited test laboratory. In planned intervals du ring the complete process, samples were taken in order to check possible mechanical changes based on a tensile test.

The used irradiation rate is equivalent to more than 10 years in the city of Assuan, Egypt (one of the highest yearly UV-radiations worldwide).

  • UV resistant (10 years warranty)
  • Easy installation
  • No corrosion
  • Increased flow rate
  • High demands for hygiene
  • High chemical resistance

POLYMELT UV resistant piping system for outdoor applications

UV radiation can be a serious challenge to plastic piping systems, affecting their durability and lifespan. However, with Polymelt’s UV resistant PP-R plastic pipes, you can rest assured that your outdoor piping system is built to last. Our advanced and durable polypropylene (PP-R) piping solution has been rigorously tested under the toughest conditions to ensure that it is highly resistant to UV radiation.
