Understaning The Pour Point Depressant Mechanism

Pour point depressants are chemically synthesized polymers or condensates that contain polar groups (or aromatic nuclei) and alkyl chains similar to paraffin structures. Pour point reducer cannot prevent paraffin from crystallizing and precipitating at low temperature, that is, the turbidity point of oil remains unchanged. It changes the shape and size of wax crystal by adsorption on the surface of wax crystal or eutectic with wax, and prevents wax from forming three-dimensional network structure, so as to maintain the flow capacity of oil at low temperature. It should be emphasized that the pour point depressant can only play a role in the oil containing a small amount of wax.

KAFTON pour point depressant products are SCR-248, SCR-158, T808A, T808B.
