Heavy Slack Wax
What is Heavy Slack Wax ?
Heavy slack wax is a type of slack wax that has a higher melting point and a higher viscosity compared to regular slack wax. It is typically produced as a byproduct of the dewaxing process used to manufacture lubricating oils and other petroleum products.
Heavy slack wax has a higher oil content and is darker in color than regular slack wax, making it more suitable for use in applications that require a higher level of lubricity or moisture resistance. It is commonly used in the production of products such as candles, polishes, and coatings, as well as in the manufacture of industrial lubricants and rubber products.
Heavy slack wax can be further refined to remove impurities and improve its properties for specific applications. The refining process involves solvent deoiling, which removes excess oil and improves the color and odor of the wax. The resulting product is known as refined heavy slack wax.
Quality of Heavy Slack Wax
The quality of heavy slack wax can vary depending on several factors, such as the production process, the source of the crude oil, and the degree of refinement. Generally, the quality of heavy slack wax is determined by its physical and chemical properties, which can impact its performance in various applications.
Some of the key properties that affect the quality of heavy slack wax include:
Melting point: Heavy slack wax typically has a melting point range of 65-80°C. The melting point affects the viscosity and flow characteristics of the wax and can impact its suitability for specific applications.
Color: Heavy slack wax can range in color from light yellow to dark brown, depending on the degree of refining. Darker colored waxes typically have higher oil content and may have a stronger odor.
Penetration: The penetration value indicates the hardness of the wax and its ability to soften at elevated temperatures. Heavy slack wax typically has a penetration value of 10-40 dmm.
Oil content: Heavy slack wax has a higher oil content than regular slack wax, typically ranging from 10-30% by weight. The oil content affects the lubricating properties of the wax and can impact its suitability for specific applications.
Solubility: Heavy slack wax is insoluble in water and has limited solubility in organic solvents. This property can affect the ease of processing and formulation of the wax in various applications.
It's important to consider these properties when selecting a heavy slack wax for a specific application and to ensure that the wax meets the required specifications and quality standards. It's also important to source the wax from a reputable supplier who can provide reliable quality assurance and technical support.
History of Heavy Slack Wax
The history of heavy slack wax is closely tied to the development of the petroleum industry, which began in the mid-19th century. As crude oil was discovered and refined, byproducts such as slack wax were produced.
The first documented use of slack wax in commercial applications was in the late 19th century, when it was used as a raw material for the production of candles. At that time, the wax was simply a byproduct of the refining process and was considered a low-value commodity.
However, as the demand for petroleum products increased in the 20th century, the production and use of slack wax also grew. The wax was found to have a wide range of applications, including as a raw material for the production of rubber, adhesives, and coatings, as well as in the manufacture of candles, polishes, and cosmetics.
With the development of new refining technologies, heavy slack wax with higher melting points and viscosities became available, providing new opportunities for its use in industrial applications. Today, heavy slack wax is used in a wide range of industries, from automotive and aerospace to cosmetics and personal care.
Overall, the history of heavy slack wax is closely tied to the growth and evolution of the petroleum industry, and the ongoing development of new applications and refining technologies continues to drive its use and value.
Usages of Heavy Slack Wax
Heavy slack wax has a wide range of applications across various industries. Some of the most common usages of heavy slack wax include:
Candles: Heavy slack wax is a popular raw material for the production of candles, particularly for high-end candles that require a longer burn time and better fragrance retention.
Polishes and coatings: Heavy slack wax is used in the manufacture of polishes and coatings for floors, furniture, and other surfaces. It provides a protective barrier and enhances the shine and appearance of the surface.
Rubber and plastic production: Heavy slack wax is used as a processing aid and lubricant in the manufacture of rubber and plastic products. It helps to improve the processing efficiency and can also improve the final properties of the products.
Adhesives: Heavy slack wax is used as a component in hot-melt adhesives to provide tackiness and improve adhesion properties.
Personal care products: Heavy slack wax is used in the production of cosmetics and personal care products such as lipsticks, lotions, and hair care products. It provides emollient and moisturizing properties.
Industrial lubricants: Heavy slack wax is used in the production of industrial lubricants for applications such as metalworking and wire drawing. It provides excellent lubricity and water resistance.
Textile industry: Heavy slack wax is used in the textile industry as a lubricant and sizing agent for yarns and fibers. It can also be used as a softener and water repellent.
Overall, the diverse properties of heavy slack wax make it a valuable raw material for a wide range of applications across various industries.
Packing of Heavy Slack Wax
Heavy slack wax is typically packed in a variety of containers to meet the specific needs of the application and the customer. Some of the most common packing options for heavy slack wax include:
Bags: Heavy slack wax can be packed in 25 kg or 50 kg bags made of woven polypropylene or paper.
Cartons: Heavy slack wax can be packed in cartons made of corrugated cardboard, typically containing 25 kg or 50 kg of wax.
Drums: Heavy slack wax can be packed in steel drums with a capacity of 180 kg or 200 kg. The drums are typically lined with a plastic bag to prevent wax leakage.
Bulk: Heavy slack wax can be transported in bulk in tank trucks or containers. In this case, the wax is typically heated and pumped to maintain its fluidity during transport.
It's important to select the appropriate packing option based on the specific needs of the application, as well as to ensure that the packaging materials are of high quality and meet any applicable regulatory requirements. It's also important to handle heavy slack wax carefully during transport and storage to prevent damage or contamination.
Prices of Heavy Slack Wax
The prices of heavy slack wax can vary depending on a variety of factors such as the quality, quantity, and location of the product. Additionally, prices can be affected by global supply and demand dynamics, as well as changes in the cost of raw materials and production.
As of my knowledge cutoff date of September 2021, the average price of heavy slack wax was around $800-$1000 per tonne. However, prices can fluctuate over time, and it's important to check current market prices to get an accurate understanding of the cost.
It's also worth noting that prices can vary between suppliers, so it's important to shop around and compare prices before making a purchase. Additionally, some suppliers may offer discounts for larger orders or long-term contracts, which can help to reduce costs.
