Slack Wax: Uses, Key Properties and Specifications

Slack wax is an intermediate product in the petroleum refining process that is gaining prominence across various industries for its versatile applications. This by-product, primarily composed of paraffin wax and oil, is widely used due to its unique properties and cost-effectiveness. In this comprehensive blog, we will delve into the uses, specifications, advantages, and potential drawbacks of slack wax, highlighting Paraffin Co. as a reliable supplier of this valuable resource.

What is Slack Wax?

Slack wax is a petroleum by-product obtained during the refining of lubricating oils. It consists of a mixture of oil and wax, typically containing between 5-30% oil content. The product’s quality and characteristics can vary significantly depending on the oil content and the specific refining process used. Slack wax is generally categorized into two types based on its oil content: light slack wax and heavy slack wax.

Key Properties

Production of Slack Wax

Slack wax is produced during the refining process of crude oil. The production involves several stages:

  1. Distillation: Crude oil is heated and distilled to separate various components, including lubricating oils.
  2. Solvent Dewaxing: The lubricating oils are further processed through solvent dewaxing, where solvents like methyl ethyl ketone (MEK) and toluene are used to precipitate wax from the oil.
  3. Separation: The wax-oil mixture is then separated, resulting in slack wax with varying oil content.
