Paraffin wax, sometimes called petroleum wax, is a white or colorless wax derived from petroleum, coal, or oil shale. Specifically, it is derived from the raw material slack wax. It consists of hydrocarbon molecules containing between 20 and 40 carbon atoms and bears the general formula of CnH2n+2. It has a solid form at room temperature. Paraffin wax has a melt point of 37°C (99°F), a boiling point of over 370°C (698 °F), and a combustion point of 245°C (473°F).

Paraffin wax has many desirable properties that make it useful in various industrial applications and consumer products, from coatings and sealants to candles and packaging. It has a smooth texture and low thermal conductivity. It is non-toxic, water-resistant, and antibacterial. It is also cost-effective, making it a popular choice for businesses looking to get the best return on their investment. 

This post will explore a few of the leading industrial applications of this useful and highly versatile wax. 

1. Paints, Coatings and Sealants

Due to its moisture-repelling properties, paraffin wax is used to enhance water resistance in paper, cardboard, and wood coatings. It is also found in food packaging products such as wax-coated paper cups and wrappers. 

In addition, paraffin wax is used in the industrial sealants industry, offering enhanced protection against liquid damage and corrosion. It improves sealants’ flexibility, adhesion, and chemical and UV resistance. 

In the paint industry, paraffin wax can enhance paint quality by assisting in the formation of a smooth and uniform finish, improving the flow of paints, adding a glossy finish, and boosting resistance to scratches, wear and tear. 

2. Candle Making Industry

Paraffin was first produced in 1830 and has been used in candle making ever since, representing a significant step forward for the candles and fragrances space. 

Paraffin wax has an excellent “scent throw,” meaning that scented paraffin candles give off a more potent smell. This property makes it desirable for scented products such as tealight candles, votive candles, container candles, and wax melts. Paraffin wax retains its fragrance for longer and offers a more vibrant light, lower melt point, and cleaner burn than many other options. Candles made from paraffin wax also typically offer a long burn time, extending their life. In addition, it is cheaper and easier to work with than many alternatives. 

Makers often combine paraffin wax with stearic acid to create candles. Stearic acid acts as a hardener and increases the opacity and solidity of the candles. It also increases the melt point of candles, making them burn hotter.

3. Packaging Industry

In the packaging industry, paraffin wax is typically added to corrugated boxes and cartons to increase durability. Depending on production processes and use cases, packaging may be coated, laminated, or impregnated with paraffin wax. Coating means applying the wax to the product’s outer surface, laminating refers to applying wax between two materials or layers of material, and impregnating means driving the wax into the material’s surface. 

Because it is non-toxic, paraffin wax is ideal for enhancing barrier properties in food-grade packaging, enhancing food safety, and keeping produce fresh for longer.

Paraffin wax can also be used in food preservation. For example, the cheesemaking industry uses a version of paraffin wax modified to make it more flexible and pliable to coat cheeses and prevent mold growth while they age. 

4. Rubber and the Tire Industry

Paraffin wax is an anti-ozonant that prevents degradation and cracking in rubber caused by ozone. This makes it an important component in the production of tires and other rubber products. Tire waxes help extend the tires’ lifespan and better enable them to withstand harsh conditions. 

In addition, paraffin wax helps with the processing and shaping of rubber materials. It can soften rubber, improve its flexibility, and allow it to maintain its properties in high-temperature environments. It can also be used as a machine lubricant, making manufacturing easier and protecting machines from damage. 

Paraffin is sometimes blended with microcrystalline wax to enhance its flexibility and adhesion when used on rubber. 

5. Textiles and the Leather Industry

Paraffin wax is commonly used in fabric finishing, particularly for waterproof, protective, and weather-resistant clothing, to add or enhance water repellency and stain resistance and create a smooth, wrinkle-free appearance.

Paraffin wax is also commonly used in leather treatments to improve leather products’ texture, durability, and softness. It can help restore shine and color to damaged leather and protect it from scuffs and scratches. 

Paraffin wax can be applied to fabric in several ways, including spraying, dipping, or using a liquid wax emulsion (a mixture of wax and water). 

Foots oil, a petroleum byproduct of paraffin wax manufacturing that is solid at room temperature and has a melt point of 40 – 60°C, is also used in the textiles, leather, and rubber industries.

6. Pharmaceutical and Cosmetic Uses

Paraffin wax is a key component in the formulation of many cosmetic and body care products, such as ointments, creams, and lip balms. Petroleum jelly, for example, is popular for treating minor skin ailments. It acts as a moisturizer, protecting the skin from moisture loss, and can relieve the symptoms of many dry skin conditions. Paraffin wax is a popular choice for these applications because it is colorless, tasteless, and odorless.

Paraffin wax also has many uses in the pharmaceutical industry. It provides a protective layer for tablets and can delay the release of active ingredients. It is also used in heat treatments to relieve stiffness and pain caused by joint conditions such as arthritis. 

7. Electrical and Mechanical Applications

Paraffin wax helps produce or enhance insulation in wires and other electrical components. Its low electrical conductivity makes it ideal for this purpose. It can also help to shield components from moisture and water damage and regulate the temperature of sensitive devices. 

In addition, paraffin wax is an ideal lubricant for industrial machines. It reduces friction and protects machines from wear and tear, ultimately extending their lifespan.
