Chemical Resistance Polyethylene - PE

Chemical resistance of polyethylene - PEH - pipes

Polyethylene is a very popular material for pipes. It is

• easy and light weighted
• long living
• low friction
• relatively cheap
• flexible
• sun resistant

and resistant to chemicals. Chemical resistance to some common chemicals:
