Microcrystalline wax is a high-melting-point, fine-crystalline hydrocarbon mixture produced from petroleum distillation residues through deep refining and deoiling. Its key characteristics lie in its flexibility, adhesion, and thermal stability, which are significantly superior to those of ordinary paraffin.
Oil Content Control: High-quality industrial-grade products typically have an oil content below 2%. Lower oil content results in higher hardness and minimal shrinkage, while slightly higher oil content provides better flexibility and adhesion.
Color and Luster: It typically appears as milky white to pale yellow granules or lumps with a light color. It develops a luster when rubbed, which is advantageous for the production of light-colored products.
Solubility and Compatibility: Insoluble in water and cold ethanol, but soluble in organic solvents such as benzene and chloroform; miscible with various mineral and vegetable waxes, and capable of raising the melting point of wax blends.
