Pour point depressant
| Oil glossary |
- An additive which retards the adverse effects of wax crystallization, and lowers the pour point.
- An additive which lowers the pour point of petroleum products containing wax by reducing the tendency of the wax to collect into a solid mass.
- An additive in lubricating oil that lowers the pour point, by preventing any wax present from crystallizing to form a solid mass.

Crystallization, английский
The formation of highly-ordered substances (crystals) from solutions or melts. in polymers, crystalline areas are interspersed with amorphous areas in a lattice-like network. (also see macrolattice.)

Pour stability, английский
The ability of a pour depressed oil to maintain its original astm pour point when subjected to long-term storage at low temperature approximating winter conditions.
Pour point, английский
- Lowest temperature at which an oil or distillate fuel is observed to flow, when cooled under conditions prescribed by test method astm d 97. the pour point is 3°c (5°f) above the temperature at which the oil in a test vessel shows no movement when the container is held horizontally for five seconds.
- Of a fuel oil, nominally the temperature three degrees c above which the fuel will just flow under its own weight. a measure of the low temperature flow characteristics of a fuel,
- A widely used low-temperature flow indicator, depicted as 5°f above the temperature to which a normal liquid petroleum product maintains fluidity. it is a significant factor in cold-weather start-up.
- Lowest temperature at which a liquid petroleum product will flow when it is cooled under the conditions of the standard test method.
- (astm d-97) the lowest temperature at which a lubricant will pour or flow under specified conditions.
- Температура металла при разливке
