Slack Wax is derived from lubricating oils and are less refined high oil products. These high oils have relatively high oil content and processed further to produce more refined waxes. Most slack waxes do not meet FDA requirements for food packaging.

Slack Wax is a translucent crystalline material in the solid state and a yellow, clear liquid when molten. Slack wax verifies from light to heavy grades based on its melting point. Melting point 50-52 ˚C is categorized in light grades and 53-55 ˚C is the heavy grade, and their oil content ranges from 5.0% to as much as 35%. One of the many products derived from refining is lubricating oil, from which a by product called slack wax is obtained. Slack wax is the crude wax produced by chilling and solvent filter-pressing wax distillate.

There are basically three types of slack wax produced, the type depending on the viscosity of the lube oil being dewaxed: low neutral, medium neutral, and heavy neutral. Slack wax is a mixture of oil and wax, obtained from lubricating oil. Slack wax is the crude wax produced by chilling and solvent filter-pressing wax distillate. It serves as feedstock and that is further refined and blended to create value-added petroleum wax products. Slack waxes are widely used in the production of wax emulsions, construction board, matches, Glass wool and textile treating, synthetic firelogs, matches, inks, weed bars, carbon paper, composite wood panels, chemicals and fertilizers, Paraffin wax production and candle production, in arena footing, in soil or turf protection, polishes, in fireplace products.

Applied externally, these waxes can also function as good dust suppressants and/or controlled-release agents for various and also Rust protective products and waterproofing agents in the manufacture of various industrial products. Fully refined products may be filtered to remove color and odor. Our Slack waxes offer a wide variety of physical and performance characteristics that are suitable for use in various product and process applications; these benefits include:
- The wide range of melting points
- Blended and single distillate products
- High flash points
- High n-paraffin contents.

Recognizing the properties of slack wax will give you the ability to determine its applications in industries.

  • Water-resistant

If you rub Slack Wax and its products, for example, paraffin, on a surface or a hole, it protects the target from getting wet. This property of Slack Wax is because of its monomolecular structure. Generally, Slack Wax is considered as a defender against water penetration.

  • Thermal insulation

Slack Wax is also known as a thermal insulator. This is very useful for textile and some other industries. You can coat every surface by paraffin just to prevent heat from transferring. For instance, it is useful for filling the gap of two different septa by Paraffin if you want to imprison heat in a hypothetical space. With a high heat capacity, you can be sure about the Slack Wax application in this field.

  • Electrical insulation

Slack Wax properties cause electrical insulation which is useful in the electrical industry. The electrical insulator at this phase of the material has lots of applications. For example, you can cover boards and surfaces of electrical circuits by paraffin to prevent the whole system from any dangers.

  • Lubricant

certainly, everybody knows the importance of the lubricating process in every industry. Lubricating helps you to reduce the heat generated by motion. When a surface is drawn to another, the heat will be produced, and this is so harmful. By heat increase, the movement becomes slow. Therefore, the lubrication process will be our solution in this case.

  • Low density

This means you can add a high amount of Slack Wax to the system without any worries about the weight. A material with low density is mostly known as a light material. Light materials with high efficiencies would be beneficial in industries.

After passing some steps, Slack Wax will change into paraffin which is the main substance of the Candle. The way it works is not complicated. The first phase of the paraffin wax process is to take oil from Slack Wax. In the industry, it is called de-oiling or de-waxing. In the de-waxing step, we remove the oil completely from the Slack Wax. Good to know that this action is possible by crystallization.

Crystallization is a process in which the precursor gets heated then cooled. It gets heated, mixed with one or more solvents such as a Ketone and in the end, it is cooled. Now we have crystallized Slack Wax out of oil and solid mixture. The name of the mentioned step is filtering. Crystallizing makes filtering easier. In the end, we have solid material with an oily component.

In a histology or pathology laboratory, paraffin wax has an important use. It is used to impregnate tissues for sectioning. Water is excluded from the tissue through ascending strengths of alcohol. In the following process, the tissue would be clear and clean in an organic solvent such as xylene and it will be put inside the paraffin wax. After a couple of hours when wax gets solid, sections can be cut on a micro-tome. But this isn’t the only use of this substance.

Another use of paraffin wax is chiefly artistic. Nowadays Wax Carving is so popular among the customers. The procedure is easy and interesting. Usually, tools like saws, specific knives, and sandpapers are used to shape Wax into statues that we want. Handicrafts have a wide market and they are high on demand. Slack Wax which we (Infinity Galaxy) supply, is the best substance for producing Wax which you need for the wax carving technique.

Another industry that has Slack Wax in its list of requirements is the textile industry. For thermal insulation and protecting some cloth with specific applications, Slack Wax and paraffin are recommended. Paraffin is applied for coating textiles. This coating is necessary to protect cloth which is obligatory for some needs. As a matter of fact, paraffin is a very appropriate material to avoid heat or chill.

The next application is a little bit different. Now, let’s move to the food-grade paraffin. In the following, we list some of its applications in food industries:

  1. As a Sealant
  2. As an Additive to Produce Chewing Gum.
  3. As a Shiny Material to Coat Candies

It is possible to coat candies with paraffin to make them more attractive. Paraffin isn’t harmful because with no digestion it passes through the digestive system.
Paraffin is also applicable to investment casting. A lubricating bullet is another common application of Wax. In weapon and gunnery industries it is very important to lubricate bullets for helping their moving process.

It is impossible to produce crayons without Slack Wax. Paraffin produced from Slack Wax is one of the primary substances of crayons. It helps crayons to be smooth to use.

One of the important applications of paraffin is in Rocket industries. As a Solid propellant for hybrid rocket motors, paraffin is so important in this era. Slack Wax uses are more extensive than what we think. Another important application is using it as an antiozonant.
