What is PEX/EVOH Oxygen Barrier pipe?
PEX/EVOH Oxygen Barrier pipe combines the benefits of PEX and EVOH. Oxygen can cause corrosion or degrade the system over time. That means that what is particularly important in applications is to prevent oxygen from entering the plumbing or heating system. PEX/EVOH Oxygen Barrier pipes can do this. It offers enhanced protection against oxygen-related issues, making it suitable for a wider range of applications by incorporating the EVOH layer.
What is PEX Non-Barrier pipe?
PEX, or cross-linked polyethylene, is a flexible, durable, and heat-resistant type of plastic pipe commonly used in plumbing and heating systems. It is renowned for its ease of installation and resistance to corrosion.
What is EVOH?
Ethylene-vinyl alcohol (EVOH) is a polymer that serves as an effective barrier against oxygen and other gases. It is utilized as a thin layer on PEX pipes to prevent the ingress of oxygen into the system.
