They are often used in premium products, sometimes serving as substitutes for higher priced natural waxes, or they may be blended with petroleum waxes
for value added applications.
The use of petroleum waxes
to protect or assist in the protection of double bonded elastomers from the destructive effects of ozone has long been known, while the mechanism by which these petroleum hydrocarbons fulfill their protective functions has more recently been elucidated, and can be followed by the analytical technique of high temperature gas chromatography.
* Loobwax 0597 - Intermediate petroleum wax

This guide briefly describes 580 tests used to characterize the chemical and physical properties of crude oils, gasoline, lubricating oils, additives, transmission fluids, gear oils, aviation fuels, diesel and heating fuels, and petroleum waxes
. Arranged alphabetically by property, each entry explains the purpose of the test, assesses its advantages and limitations, summarizes how the test is performed, and cites precision ranges.
Much of the petroleum remaining underground tends to be heavy (containing petroleum waxes
, which make the oil harder to pump) and sour (meaning high in sulfur and other contaminants).
Penreco is a leading refiner and processor of specialty hydrocarbon products such as White Mineral Oil USP, Petroleum Waxes
, Petrolatum, Hydrocarbon Gels and well-respected quality brands such as Drakeol[R], Versagel[R] and Synergel[R].
