The wax is a kind of mineral wax, also be a kind of petroleum wax, It is from crude distillation income lubricating oil fractions by solvent refined, solvent dewaxing or by wax frozen crystallization, squeezing dewaxing made cerate, again by solvent oil refining and get off the flake or needle crystal. Also called crystal shape wax, carbon atom number about 18 ~ 30 of hydrocarbon mixtures, mainly group is divided into linear paraffins (approximately 80% ~ 95%), and a small number of individual up the chain with linear alkanes and take long side chain monocylic cycloparafin hydrocarbon (together content 20% below). Main quality indicators for melting point and oil content, the former said heat-resistant ability, who said purity. Among them before their USES a broader, mainly for food and other commodities (such as wax paper, crayons, candles, carbon) components and packaging materials, roasted container besmear dressings, cosmetic raw material, used for fruit fresh and improving rubber anti-aging properties and increase flexibility, electrical components insulation, precision casting, etc, also can used for oxidation generating synthetic fatty acids
