PARAFFIN WAX
Paraffin wax is a kind of petroleum processing products, mineral wax and petroleum wax. It is a kind of flake or needle like crystal which is obtained from the crude oil distillation by solvent refining, solvent dewaxing or wax freezing crystallization and pressing dewaxing. It is used for making high-grade fatty acid, high-grade alcohol, match, candle, waterproof agent, ointment, electrical insulating material, etc
Fully refined paraffin wax
Fully refined paraffin wax is widely used, mainly for food, oral medicine and some products (such as wax paper, crayons, candles, carbon paper) components and packaging materials, baking container coating, used for fruit preservation, electrical components insulation, improve rubber anti-aging and flexibility.
Strength& Applications
Paraffin wax, as a kind of latent energy storage material, has the advantages of large latent heat of phase change, small volume change of solid-liquid phase change process, good thermal stability, no supercooling phenomenon and low price. With the development of aviation, aerospace, microelectronics and Optoelectronics Technology, it is often required that a large amount of heat dissipation generated by high-power components can only be dissipated in a limited heat dissipation area and a very short time, while the low melting point phase change materials can reach the melting point relatively quickly compared with the high melting point phase change materials, making full use of the latent heat to achieve temperature control, and the thermal response time is relatively short, which is due to many advantages of paraffin. Aerospace, microelectronics and other high-tech systems, as well as housing energy saving and other fields have been widely used.
