Microcrystalline wax is amorphous solid wax, also known as purified ground wax. It is prepared from vacuum residue by solvent deasphalting, solvent dewaxing, deoiling, refining, shaping, and packaging. Its chemical composition is less than normal alkanes. The main components are cyclic hydrocarbons with normal or isomeric alkyl side chains, especially naphthenic hydrocarbons. The larger the molecular weight, the higher the content of isomers and long chain alkanes. Microcrystalline wax has the characteristics of small hardness, good flexibility, and stress, and tends to plastic flow, high elongation, good flexibility, and strong gel strength. With its unique properties, amorphous wax is widely used in emulsion explosives, rubber, hot melt adhesives, crayons for cultural and educational supplies, rubber mud, wax paper, ink, lubricant, paint, polishing, spinning wax, casting mold, electrical and electronic insulation, medicine, cosmetics, food, and food packaging, etc.
