Understanding Slack Wax: Composition and Characteristics

Slack wax is produced during the refining of lubricating oils. It is a mixture of oil and wax, typically containing 10-30% oil content, and is categorized by its oil content and melting point. The composition of slack wax can vary, but it generally includes:

  • Paraffin Wax: The main component, providing the bulk of the physical properties of slack wax.
  • Oil Content: Varies depending on the grade, influencing the wax’s consistency and melting point.
  • Other Hydrocarbons: Minor components that can affect the performance and characteristics of the wax.

Key Characteristics of Slack Wax

  • Melting Point: Typically ranges from 45°C to 65°C, depending on the oil content and specific blend.
  • Colour: Generally off-white to yellowish, influenced by the refining process and oil content.
  • Viscosity: Varies with temperature and oil content, affecting its application and performance.
  • Solubility: Soluble in organic solvents, making it versatile for various industrial applications.
