Pour Point Depressants 

Pour Point Depressants 

  • Pour Point Depressants act as a wax crystal modifier. Modification is achieved by nucleation, co-crystallization and anti-agglomeration, which results in reduction of the size and shape of wax crystals. Wax-crystals are not inhibited but modified in a way that they do not precipitate.
  • Standard test methods applied include ASTM D 97 / DIN ISO 3016 or ASTM D 5985.
  • The performance of a Pour Point Depressant does not only depend on the concentration and distribution of linear n-paraffin’s, but is also influenced by Asphaltenes and other components.
