Microcrystalline wax: microcrystalline wax is an approximate the microcrystalline nature refined synthetic wax, odorless, tasteless, white amorphous amorphous solid wax. It is from the residue remaining after the fractionation of petroleum, long chain hydrocarbons, its main ingredient is a C31-70 branched chain saturated hydrocarbon obtained by solvent extraction and chemical treatment methods, a high boiling point, a small amount of a cyclic, branched chain hydrocarbon, melting point to 60-85 ° C, with a variety of mineral wax, vegetable wax and hot fat oil miscible. Such wax particulate, and having a ductility, not fragile at low temperature, and then mixed with a liquid oil to prevent oil separation characteristics of the precipitated. M.p. extent ductile at 77-80 ℃ microcrystalline wax, Similar soft ceresin, melting at 88-90 ° C. The microcrystalline wax is hard, the appearance such as montan wax (lignite wax). Good gloss, high melting point, light color, compact structure, strong and smooth, with a variety of natural wax melting each other, and can improve the low melting point of the wax to improve the performance of crude wax. Microcrystalline wax white jade, friction and light, a very favorable effect on the production of light-colored products.
