Physical properties of paraffin

Paraffin, also known as crystalline wax, is usually a white, odorless waxy solid, melted at 47 °C-64 °C, with a density of about 0.9g/cm3, soluble in gasoline, carbon disulfide, xylene, ether, benzene, chloroform, carbon tetrachloride, naphtha, etc. Pure paraffin wax is a good insulator, with a resistivity of 1013-1017 ohm-meters, which is higher than most materials except for certain plastics, especially Teflon. Paraffin wax is also a good heat storage material, with a specific heat capacity of 2.14-2.9J·g–1· K–1, heat of melt is 200–220 J·g–1. The main performance indicators of paraffin wax are melting point, oil content and stability.
