Paraffin wax, also known as crystalline wax, is soluble in non-polar solvents such as gasoline, carbon disulfide, xylene, diethyl ether, benzene, chloroform, carbon tetrachloride, and naphtha, but insoluble in polar solvents like water and methanol.It is mainly used as a component and packaging material for food, oral pharmaceuticals, and certain products (e.g., waxed paper, crayons, candles, carbon paper), as a coating for baking containers, for fruit preservation, insulation of electrical components, improving the aging resistance and flexibility of rubber, etc. It can also be used to produce synthetic fatty acids via oxidation.

Crude paraffin wax has a relatively high oil content and is mainly used in the manufacture of matches, fiberboards, canvas tarpaulins, etc.After adding polyolefin additives to paraffin wax, its melting point increases, and its adhesion and flexibility are improved. It is widely used in moisture-proof and waterproof packaging paper, cardboard, surface coating of certain textiles, and candle production.
