Detailed Product Description

A semi-refined wax, distinguished from scale wax by having a generally higher oil content. Semi-refined slack waxes may have oil contents up to 30 mass percent.  Slack waxes with oil content below 10 mass percent are used for manufacture of religious candles.  Slack wax is the crude wax produced by chilling and solvent filter-pressing wax distillate. There are basically three types of slack wax produced, the type depending on the viscosity of the lube oil being dewaxed: low neutral, medium neutral, and heavy neutral.

Soft, semi

Crude wax, also called petroleum wax or slack wax, is an unrefined mixture of high-melting hydrocarbons, mainly of the normal straight-chain type, still containing a fairly high percentage of oil. It is obtained by filtration(as such or after addition of a solvent)from high boiling distillates or residual oils. Slack wax is primarily obtained as by-product in the manufacture of lubricating oils. The crude wax made from distillate oils is used for the manufacture of scale wax and paraffin wax or serves as a feedstock for the manufacture of petroleum chemicals such as synthetic detergents. The crude wax made from residual oils is refined to make a range of microcrystalline waxes. (1).
