2.1.2Chemical properties

HPL is resistant to most chemicals. Some chemicals, however, can affect the surface. Special consideration must be given to:

  • the concentration of the chemical
  • the pH value (acid/base ratio)
  • the exposure time
  • the temperature
     

The list shown in appendix 2 provides – without claiming to be complete –  an overview of the resistance, limited resistance, lack of resistance of HPL to the most commonly used substances (in solid, dissolved or gaseous form). If chemicals other than those listed in the appendix are intended for contact with HPL, their compatibility must be tested.
