Slack Wax; Its Uses, Applications, Advantages & Disadvantages, and Price Factor

Slack wax is an intermediate material obtained during the refining process of lubricating oils. It is a mixture of oil and wax, primarily composed of paraffin and microcrystalline waxes. Slack wax plays a crucial role in various industries due to its versatile properties and applications. This blog will provide an in-depth understanding of slack wax, its uses, applications, advantages, and disadvantages, along with the factors influencing its price. Peak Universal Business is a prominent supplier of high-quality slack wax, ensuring reliable products for diverse needs.

What is Slack Wax?

Slack wax is a crude wax containing a high percentage of oil, typically ranging from 5% to 20%. It is derived from the dewaxing process of petroleum-based lubricating oil production. The dewaxing process involves chilling the oil to crystallize the wax, which is then separated and collected as slack wax. Depending on the oil content and refining process, slack wax can be categorized into two main types: light slack wax and heavy slack wax.

Production Process

1. Dewaxing: Lubricating oil is chilled to crystallize the wax content.
2. Filtration: The crystallized wax is separated from the oil through filtration or centrifugation.
3. Slack Wax Collection: The separated wax, containing a significant amount of oil, is collected as slack wax.
4. Further Processing: Slack wax can be further refined to produce paraffin wax, microcrystalline wax, or other wax products.

Uses of Slack Wax

Slack wax has a wide range of uses across various industries due to its unique properties. Some of the primary uses include:

1. Candle Manufacturing: Slack wax is a key ingredient in candle production, providing the necessary wax content and improving the burning quality.
