POLYMELT UV PP Piping System.
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.
Our UV resistant plastic pipes and fittings are designed to withstand continuous exposure to sunlight, and will not rust, calcify, corrode, or crumble over time. With decades of virtually maintenance-free use guaranteed, our UV resistant PPR pipes are a smart investment for any outdoor piping system.

PPR Pipe for Outdoor – Durable and UV-Resistant with POLYMELT UV
Using standard PPR pipes in outdoor applications often leads to significant issues due to exposure to UV radiation. Prolonged sunlight weakens conventional PPR pipes, causing surface degradation, discoloration, and the formation of micro-cracks. Over time, this can result in reduced mechanical strength, brittleness, and ultimately, pipe failure. These problems not only shorten the lifespan of the piping system but also increase maintenance costs and the risk of leaks or system downtime.
POLYMELT UV eliminates these challenges with its advanced UV-stabilized layer, providing superior protection against harmful sunlight. Unlike regular PPR pipes, POLYMELT UV maintains its strength, color, and performance, even after years of outdoor exposure.
Ideal for outdoor plumbing, irrigation systems, and solar water heating, POLYMELT UV pipes resist discoloration, surface damage, and the need for additional coatings or coverings. Choose POLYMELT UV for a long-lasting, UV-resistant PPR pipe solution designed specifically for outdoor use.
