What is Slack Wax
Slack wax is the by-product of the base oil refinery process which is a mixture of oil and wax. Slack wax is fed into the system as raw material which is finally processed into different grades of paraffin wax after performing the refining processes, de-oiling and bleaching.
Slack wax is naturally brown in color and depending on the viscosity of the lube oil being de-waxed it is categorized in two types of light and heavy. In light grades the melting point is 50-52˚C where in light grades the melting point is 53-55˚C is the heavy grade and their oil content ranges from 5.0% to 35%.
Usually light slack wax is processed for production of fully-refined paraffin wax which can be used in cosmetics and food industries while heavy slack Wax is usually processed into semi-refined paraffin wax which contains higher weight percentage of oil and applicable in candles, rubbers, adhesive, hot melts and ink industries.
