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:
