Overview
Slack Wax is mixture of paraffin wax and oil originated from petroleum crude oil. Slack Wax oil content can range from 10% to 30%. Slack Wax is produced during the production of Group I lube base oil. Behran Slack Wax Can be used as blending components or water proofing agent in the manufacture of various industrial products such as candles, canvass coatings and composite wood panels. These waxes can also function as controlled release agents for various chemicals and fertilizers. Slack Wax is derived from lubricating oils and are less refined high oil products. These high oils have relatively high oil content and processed further to produce more refined waxes. Most slack waxes do not meet FDA requirements for food packaging.
Manufacturing Process
Slack Wax is a translucent crystalline material in the solid state and a yellow, clear liquid when molten. Slack wax verifies from light to heavy grades based on its melting point. Melting point 50-52 ˚C is categorized in light grades and 53-55 ˚C is the heavy grade, and their oil content ranges from 5.0% to as much as 35%. Slack waxes and petrolatums formed in the dewaxing process contain substantial amounts of oil, usually 10-30 wt- %. “Oil” in this sense is a mixture of the components dissolved in the solvent at the filtration temperature, and seriously impairs some properties of the wax important for its use. Wax fractions already crystalline at the temperature of dewaxing, but having relatively low melting points and consisting mainly of iso-alkanes have similarly detrimental properties. For this reason, these substances, that is, oil and low-melting fractions must be removed from the slack wax. The process is called de-oiling. De-oiling is the fractional crystallization of slack or paraffin waxes by their melting point.
