what is difference in PPR and UPVC material durability

Both PPR (Polypropylene Random Copolymer) and UPVC (Unplasticized Polyvinyl Chloride) are commonly used materials in plumbing and piping systems, but they have some differences in terms of durability.

1. Chemical Resistance: PPR has excellent chemical resistance, making it suitable for a wide range of applications, including hot and cold water systems. It is resistant to corrosion caused by chemicals, acids, and bases commonly found in plumbing systems. On the other hand, UPVC also exhibits good chemical resistance, but it may not be as resistant to certain aggressive chemicals as PPR.
2. Temperature Resistance: PPR has a higher temperature resistance compared to UPVC. It can withstand continuous operating temperatures of up to 90°C (194°F) in plumbing applications. This makes it suitable for hot water distribution systems. UPVC, on the other hand, has a lower temperature resistance and is typically used for cold water applications. It can typically handle temperatures up to 60°C (140°F).
3. Pressure Resistance: PPR has good pressure resistance, allowing it to withstand higher pressure levels in plumbing systems. It can handle operating pressures of up to 25 bar (362.6 psi), depending on the pipe size and wall thickness. UPVC can also handle moderate pressure levels, but it may not be suitable for applications requiring high-pressure resistance.
4. Impact Strength: PPR has excellent impact strength, making it resistant to cracking or breaking under mechanical stress or impact. This property ensures its durability and longevity in plumbing systems. UPVC also has good impact strength, but it may be relatively more susceptible to damage under certain conditions compared to PPR.
5. UV Resistance: UPVC has good resistance to ultraviolet (UV) radiation, making it suitable for outdoor applications where exposure to sunlight is a concern. PPR, on the other hand, may not be as resistant to UV radiation, and prolonged exposure to sunlight can degrade its properties over time.

It’s important to consider the specific requirements of your plumbing application and consult with professionals or adhere to relevant plumbing codes and standards to determine the most appropriate material for your needs. Both PPR and UPVC are widely used and have proven durability in plumbing systems when used correctly in their intended applications.
