Microcrystalline wax natural vacuum oil residue as raw material, after deasphalting, refining, Ketone benzene de-oiling, white clay refining hydrotreating, and cooling and forming the system after the series of products. Microcrystalline wax has been called purified wax, refined petroleum wax, white to light yellow.
Products by color, oil content, and PAH classification are divided into qualified products, highest grade, and food grade.
According to the low melting point grade is divided into 70, 75, 80, 85, 90, a total of five grades. Microcrystalline wax white or light yellow solid, the crystal is fine, with better permeability, adhesion and toughness, and moisture, good insulation.
