Today we will analyze the source and performance indicators of paraffin wax in detail, including the price of paraffin wax.

Paraffin wax is a hydrocarbon mixture extracted from certain distillates of petroleum, shale oil or other bituminous mineral oils. The main component is solid alkanes, which is odorless and tasteless, and is white or light yellow translucent solid.

Paraffin wax is non-crystalline, but has a clear crystal structure.
 
Paraffin wax is a kind of petroleum processing product, a kind of mineral wax, and a kind of petroleum wax. It is a flake or needle-like crystal obtained by solvent refining, solvent dewaxing, or freezing crystallization of wax, pressing dewaxing to prepare the lubricating oil fraction obtained from crude oil distillation, and then solvent deoiling and refining.

Paraffin wax is divided into food grade (food grade and packaging grade, the former is excellent) and industrial grade. Food grade is non-toxic and industrial grade is inedible.

The physical properties of paraffin wax: Paraffin wax, also known as crystalline wax, is usually a white, odorless waxy solid. It melts at 47°C-64°C and has a density of about 0.9g/cm3. It is soluble in gasoline, carbon disulfide, xylene, ether, benzene , Chloroform, carbon tetrachloride, naphtha and other non-polar solvents, insoluble in polar solvents such as water and methanol.

Performance indicators: The main performance indicators of paraffin wax are melting point, oil content and stability.

Melting point:
Paraffin wax is a mixture of hydrocarbons, so it does not have a strict melting point like pure compounds. The so-called melting point of paraffin wax refers to the temperature at which the stagnation period first appears on the cooling curve when the melted paraffin wax sample is cooled under specified conditions. All kinds of wax products require paraffin wax to have good temperature resistance, that is, it does not melt or soften and deform at a specific temperature. According to the use conditions, the regions and seasons of use, and the differences in the use environment, commercial paraffin waxes are required to have a series of different melting points. 

The main factor that affects the melting point of paraffin wax is the weight of the selected raw material fraction, and the melting point of the paraffin wax from the heavier fraction is higher. In addition, the oil content also has a great influence on the melting point of paraffin wax. The more oil in paraffin wax, the lower its melting point.

Oil content 
Oil content refers to the amount of low melting point hydrocarbons contained in paraffin wax. Excessive oil content will affect the color and storage stability of paraffin wax, and it will also reduce its hardness. Therefore, the oleaginous wax paste extracted from the vacuum fraction needs to be deoiled by the sweating method or the solvent method to reduce its oil content. However, most paraffin wax products need to contain a small amount of oil, which is beneficial to improve the gloss and release performance of the products.

Stability 
In the process of modeling or coating, paraffin wax products are in a hot melt state for a long time and are in contact with air. If the stability is not good, they will be easily oxidized and deteriorated, the color will become darker, and even give off an odor. In addition, paraffin wax will turn yellow under light conditions during use. Therefore, paraffin wax is required to have good thermal stability, oxidation stability and light stability.  

The main factors affecting the stability of paraffin wax are the trace amounts of non-hydrocarbon compounds and fused ring aromatic hydrocarbons. In order to improve the stability of paraffin wax, it is necessary to deep refine the paraffin wax to remove these impurities.

According to the degree of refining, it can be divided into three types: fully refined paraffin, semi-refined paraffin and crude paraffin. Each type of wax is divided into different varieties according to the melting point, generally every 2 ℃, such as 52, 54, 56, 58, 60, 62, etc.

Paraffin wax is divided into food wax, fully refined paraffin, semi-refined paraffin, crude wax, match wax and black wax. Our paraffin wax products mainly include fully refined paraffin, semi-refined paraffin, crude paraffin, etc. The conventional product is colorless or white translucent block. This product is refined granular, odorless, tasteless, and creamy. Almost insoluble in water and ethanol, but soluble in chloroform and ether. The melting range is 50~65℃, and the relative density is 0.880~0.915.

Uses of paraffin wax:

Because of its high oil content, crude paraffin is mainly used in the manufacture of matches, fiberboards, tarpaulins, etc. After polyolefin additives are added to paraffin wax, its melting point increases, adhesion and flexibility increase, and it is widely used in moisture-proof and waterproof packaging paper, cardboard, surface coating of certain textiles and candle production.  

After immersing the paper in paraffin wax, various wax papers with good waterproof performance can be prepared, which can be used in food, medicine and other packaging, metal rust prevention and printing industries; after paraffin wax is added to cotton yarn, the textile can be soft, smooth and elastic ; Paraffin wax can also be made into detergents, emulsifiers, dispersants, plasticizers, greases and so on.  

Fully refined paraffin and semi-refined paraffin have a wide range of uses. Main ingredients: refined mixture of solid saturated paraffinic hydrocarbons (paraffins) in natural petroleum, mainly non-standard natural paraffin waxes.They are mainly used as components and packaging materials for foods, oral medicines and certain commodities (such as wax paper, crayons, candles, carbon paper), coating materials for baking containers, and preservation of fruits , Insulate electrical components, improve rubber aging resistance and increase flexibility. It can also be used for oxidation to generate synthetic fatty acids.

In addition, the paraffin wax factories are mainly distributed in Liaoning Province and are sent out at Dalian Port.

We have paraffin waxes from different refinery areas, such as Fushun Refinery, Dalian Refinery, Daqing Refinery, and Jingmen Refinery. We can provide all melting point paraffin waxes and provide prices. Due to the price of paraffin wax and market fluctuations, the price is not fixed.
