Cross-linked Polyethylene (PEX) is a plastic material made from medium- or high-density polyethylene that is modified to have improved properties such as enhanced heat resistance and long term strength and stability that make it an excellent choice for use in service lines, hot- and cold-potable water distribution …

What is the difference between polyethylene and PEX?

There are two common types of plastic piping which are known as PB (Polybutylene) and PEX (Cross-linked Polyethylene). The main difference between PB and PEX is in how the material is created. … So if you will be pumping water, or the pipes will be exposed to the cold, PEX is a better option than PB.

What material is PEX made of?
