The main uses of paraffin

Coarse paraffin, due to its high oil content, is mainly used in the manufacturing of matches, fiberboards, canopies, and canvas. After adding polyolefin additives to paraffin, 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, various wax papers with good waterproof properties can be made, which can be used in packaging of food, medicine, metal rust prevention, and printing industries; Adding paraffin to cotton yarn can make textiles soft, smooth, and elastic; Paraffin wax can also be used to produce detergents, emulsifiers, dispersants, plasticizers, lubricants, etc.

Fully refined paraffin wax and semi refined paraffin wax are widely used, mainly as components and packaging materials of food, oral medicine and some commodities (such as wax paper, crayons, candles, carbon paper), as well as coating and dressing of baking containers, for fruit preservation [3], insulation of electrical components, improvement of aging resistance and flexibility of rubber [4]. It can also be used for oxidation to generate synthetic fatty acids.

Paraffin, as a latent heat energy storage material, has the advantages of large latent heat of phase change, small volume change during solid-liquid phase change, good thermal stability, no supercooling phenomenon, and low price. The development of aviation, aerospace, microelectronics, and optoelectronic technology often requires that the large amount of heat dissipation generated during the operation of high-power components can only be dissipated within a limited heat dissipation area and an extremely short time. Low melting point phase change materials can quickly reach the melting point compared to high melting point phase change materials, fully utilizing latent heat to achieve temperature control. The relatively short thermal response time of paraffin has made it widely used in high-tech systems such as aviation, aerospace, microelectronics, and energy-saving buildings. [5]

GB 2760-96 stipulates that it is allowed to be used as a gum sugar base agent, with a limit of 50.0g/kg. Anti stick agent also used in the production of glutinous rice paper abroad, with a dosage of 6g/kg. In addition, it is widely used for moisture-proof, anti stick, and anti oil properties of food packaging materials. Suitable for components such as food chewing gum, bubble gum, and pharmaceutical virgin oil, as well as wax used for direct contact with food and drugs such as heat carriers, demolding, tablet pressing, polishing, etc. (made by cold pressing wax containing fractions of petroleum or shale oil).
