Physical properties of paraffin wax

Paraffin wax, also known as crystalline wax, is usually a white, odorless waxy solid, melting at 47 ° C -64 ° C, density of about 0.9g / cm³, soluble in gasoline, carbon disulfide, xylene, ether, benzene, chloroform, four A class of non-polar solvents such as carbon chloride and naphtha, insoluble in polar solvents such as water and methanol. Pure paraffin is a good insulator with a resistivity of 1013-1017 ohm-meter, which is higher than most materials except some plastics (especially Teflon). Paraffin is also a good heat storage material with a specific heat capacity of 2.14–2.9 J·g^–1·K^–1 and a heat of fusion of 200–220 J·g^–1. The main performance indicators of paraffin are melting point, oil content and stability.
