Paraffin wax is mostly a white, odorless, tasteless, waxy solid with a typical melting point of about 46 to 68°C (115 to 154°F) and a density of about 900 kg/m3. It is insoluble in water, but soluble in ether, benzene and certain esters. Paraffin is unaffected by most common chemicals but burns easily. Its heat of combustion is 42 megajoules per kilogram.
Paraffin is an excellent electrical insulator with a resistivity between 1013 and 1017 ohm meters. That's better than almost every other material except some plastics, especially TEflon. It is an effective neutron moderator and was used to identify neutrons in James Chadwick's 1932 experiment.
