Stability:
1. The chemical properties of paraffin wax are relatively stable, and it is not easy to interact with alkalis, inorganic acids and halogen elements. Paraffin wax melts when exposed to heat, and burns and decomposes when exposed to high heat.

Physical and chemical properties
Appearance is white solid. Melting point 50℃～70℃, relative density 0.9, average carbon chain length C28～C29, relative average molecular weight 400 varieties: 20℃ solid relative density 0.88～0.93, equivalent to Chemicalbook radiation rate 1.526～1.535, 100℃ liquid relative The density is 0.73-0.77, and the refractive index is 1.418-1.433. Soluble in benzene, chloroform, carbon tetrachloride, camphor oil, insoluble in methanol, ethanol and water.

Main application
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 paper sizing agent and a waterproof and oil-repellent coating.
2. Application in the field of industry and agriculture. Paraffin wax is widely used in industrial fields such as rubber, textile, investment casting, plastics and electronics. It can be used as anti-aging agent, softening agent, toughening agent and release agent for rubber. It can also be used as gloss finishing agent, softening agent, batik anti-dyeing agent and water repellent finishing agent for textiles.
3. Application in the field of medicine. The most widely used Chemicalbook in the field of medicine is liquid paraffin. 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, non-biotoxicity, and similar properties to biological glue.
4. Application in the field of construction. 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 floors and ceilings.
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.
