SLACK WAX

Slack wax  is yellow or brown , easy melt able product.t is one of the products of refineries which is mixture of paraffin wax and oil originated from petroleum crude oil. Slack Wax oil content can range from 5% to 30%.

It is produced during the production of Group I lube base oil. During producing  the feedstock firstly has to go through solvent extraction process to remove aromatics and the resultant product is called Raffinate. Raffinate is then diluted with solvent like methyl-ethyl ketone (MEK) to lower its viscosity to improve low-temperature filterability. The diluted oil is then chilled to -10°C to -20°C. Wax crystals will form, precipitate and removed by filtration. And the extracted wax becomes Slack Wax. 
The traditional usage of Slack Wax is in the producing paraffin wax. And other major usage are for particle board and medium density fiberboard, cable filing compound , matches, candles, rust protective products and moisture vapor barriers.
