Paraffin wax is a white or colorless soft solid derivable from petroleum, which can be processed and achived in a wide range of physical and chemical properties, using different refining methods. Paraffin waxes are mostly graded according to the oil content, ranging from around 0.5% to above 20%. The change in oil content can lead to different physical and chemical behaviours of paraffin wax.

Paraffin wax is mostly found in two types of Fully-refined and Semi-refined, with a typical melting point between about 46 and 68 °C (115 and 154 °F), and a density of around 900 kg/m3. It is insoluble in water, but soluble in ether, benzene, and certain esters. Paraffin is unaffected by most common chemical reagents but burns readily. Its heat of combustion is 42 kJ/g.

Paraffin wax is an excellent electrical insulator, with a resistivity of between 1013 and 1017 ohm metre.

Paraffin wax is also an excellent material for storing heat, with a specific heat capacity of 2.14–2.9 J g−1 K−1 (joules per gram kelvin) and a heat of fusion of 200–220 J g−1. Wax expands considerably when it melts and this allows its use in wax thermostatic element thermostats for industrial, domestic and, particularly, automobile purposes.
