What is Heavy Slack Wax 2-5%?

Heavy Slack Wax is a petroleum derivative, primarily a by-product of the lubricating oil refining process. The “2-5%” in Heavy Slack Wax 2-5% refers to the oil content in the wax, which significantly influences its applications and properties. Slack waxes generally contain higher oil content compared to fully refined waxes, making them suitable for various intermediate applications.

Production of Heavy Slack Wax 2-5%

The production of Heavy Slack Wax 2-5% involves several key steps within the petroleum refining and wax processing industries:

  1. Crude Oil Distillation

The process begins with the distillation of crude oil. During this stage, crude oil is heated in a distillation column, and its components are separated based on their boiling points. Lubricating oil fractions are extracted, which later undergo further processing to produce slack wax.

  1. Solvent Dewaxing

The lubricating oil fractions are subjected to solvent dewaxing to remove the wax content. In this process, solvents such as Methyl Ethyl Ketone (MEK) or toluene are used to precipitate the wax from the oil. The mixture is cooled to facilitate the crystallization of wax, which is then separated by filtration.

  1. Separation and Collection

The crystallized wax collected from the filtration process contains a significant amount of oil, resulting in slack wax. The oil content in Heavy Slack Wax 2-5% is carefully controlled to be within the 2-5% range, providing a balance between flexibility and rigidity.

  1. Refining and Purification
