Food Grade Paraffin, Candle Making Wax

Paraffin is a hydrocarbon mixture extracted from certain distillates of petroleum, shale oil or other asphalt mineral oils. Its main component is solid alkanes, which are odorless and tasteless, and are white or light yellow translucent solids. Paraffin is a mixture of normal chain saturated alkanes of different molecular weights, which can be represented by the general formula CnH2n+2. According to the physical state of paraffin, it can be divided into three categories: liquid paraffin, solid paraffin and microcrystalline wax. Paraffin has many advantages such as low price, wide source, colorless and tasteless, stable physical and chemical properties, and large phase change latent heat. Therefore, it is widely used in medicine, packaging, construction, military camouflage, industry and agriculture. In recent years, there have been many studies on composite phase change energy storage materials.

Performance indicators

1. Melting point

Paraffin is a mixture of hydrocarbons, so it does not have a strict melting point like a pure compound. The so-called melting point of paraffin refers to the temperature at which the first stagnation period appears on the cooling curve of the melted paraffin sample under specified conditions. Various wax products require paraffin to have good temperature resistance, that is, it does not melt or soften and deform at a specific temperature. According to the differences in use conditions, regions and seasons of use, and use environments, commercial paraffin is required to have a series of different melting points. The main factor affecting the melting point of paraffin is the weight of the selected raw material fraction. The melting point of paraffin extracted from the heavier fraction is higher. In addition, the oil content also has a great influence on the melting point of paraffin. The more oil in the paraffin, the lower its melting point.

2. Oil content

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

3. Stability

During the molding or coating process, paraffin products are in a hot melt state for a long time and are in contact with air. If the stability is not good, it is easy to oxidize and deteriorate, darken the color, and even emit a bad smell. In addition, paraffin will turn yellow when exposed to light during use. Therefore, paraffin is required to have good thermal stability, oxidation stability and light stability. The main factors affecting the stability of paraffin are the trace amounts of non-hydrocarbon compounds and polycyclic aromatic hydrocarbons it contains. In order to improve the stability of paraffin, it is necessary to deeply refine the paraffin to remove these impurities.

2. Application scenarios and advantages (Advantage & Benefit)

Industry pain point solutions:

Food packaging: wax-coated paperboard moisture-proof performance increased by 40%, passed FDA food contact material certification

Candle manufacturing: high melting point models (58#-62#) reduce demoulding cracking and increase the yield by 25%

Rubber industry: as a softener to reduce the viscosity of rubber, mixing efficiency increased by 30%

Cosmetics: microcrystalline wax (matching supply) improves lipstick molding stability

Production process

1. Dewaxing.

That is, separating wax from waxy oil. If cold pressing dewaxing or solvent dewaxing is used, oil-containing paraffin can be obtained, and liquid wax can be obtained by molecular sieve or urea dewaxing.

2. Deoiling.

The oil-containing wax can be treated by sweating or solvent deoiling to remove the oil in the paraffin.

3. Refining.

The deoiled paraffin is refined with white clay to obtain white paraffin.

4. Molding.

The high-melting point paraffin is processed into block products through a molding machine.

Encapsulation method

1. Direct incorporation method. Add paraffin directly to the substrate. This method is easy to control the amount of addition, but it is prone to phase separation.

2. Immersion absorption method. Use a porous substrate to absorb paraffin for encapsulation.

3. Container encapsulation. It is divided into macro encapsulation and micro encapsulation.

Main applications

1. Application in the packaging field. Paraffin wax can improve the finish, toughness and printing quality of packaging materials, while reducing production costs. Therefore, it is often used as a papermaking sizing agent and waterproof and oil-proof coating.

2. Application in the industrial and agricultural fields. Paraffin wax is widely used in industrial fields such as rubber, textiles, investment casting, plastics and electronics. It can be used as an antioxidant, softener, toughening agent and release agent for rubber, and can also be used as a gloss finishing agent, softener, batik anti-dyeing agent and water-repellent embedding agent for textiles.

3. Application in the medical field. Liquid paraffin is the most widely used in the medical field. Liquid paraffin is an oily organic substance with strong cohesion. It is insoluble in water and cannot be saponified. It has the characteristics of good transparency, easy flow, no biological toxicity, and similar performance to biological glue.

4. Application in the construction field. Among building materials, phase change paraffin is mainly used in phase change energy storage gypsum board, phase change energy storage concrete, building thermal insulation materials, phase change energy storage mortar and phase change heat storage floor and ceiling, etc.

5. Application in the field of military camouflage. The characteristics of paraffin phase change materials have broad application prospects in thermal infrared camouflage and thermal infrared false targets.
